Absolutely yes it can be found, but we aren't close to it yet.
I think the greatest physicists who were close were Maxwell, Thompson and Tesla.
Maxwell derived the electromagnetic (EM) wave equation by considering the aether as a fluid and elastic medium.
Tesla maintained the aether was the medium for electric force.
Yet since Einstein and the Michelson-Morley experiment came along and "disproved" the aether we have made little progress.
Quantum Mechanics (QM) reduced energy waves to waves of probability.
General relativity (GR) reduced aether into an abstract "curved space-time".
Whist mathematically accurate, QM and GR have in some ways set us backwards.
Scientists are no longer exploring the aether and fundamentally EM so little recent progress has made.
String theory is a mathematical fudge to unite GR and QM, invoking non-existent multidimensional space so don't hold your breath with that.
Modern science has failed to teach the investigative thought process, and much of what is taught is learned without the question: "Where does this come from?"
Here's my TOE: m - e = time
No physical theory to date is believed to be precisely accurate. Instead, physics has proceeded by a series of "successive approximations" allowing more and more accurate predictions over a wider and wider range of phenomena. Some physicists believe that it is therefore a mistake to confuse theoretical models with the true nature of reality, and hold that the series of approximations will never terminate in the "truth". Einstein himself expressed this view on occasions.[46] Following this view, we may reasonably hope for a theory of everything which self-consistently incorporates all currently known forces, but we should not expect it to be the final answer.

What happened to Space in your equation?

First of all, nothing is the absence of something. It is not something itself. Also, it is not part of everything. Where anything that could be called everything begins, nothing stops. Where anything that could be called nothing begins, everything stops.

If solutions in classical mechanics are approximations and quantum mechanic solutions are probability distributions, then add in the limits imposed by the uncertainty principle, why should we think that a ToE is possible or even relevant? There's no “exactness” in any of the current theories. Even if some unification model was discovered, wouldn't it still be an approximation? There's nothing exact in this universe to work with. The singularity of a black hole is infinity. Any calculation which includes infinity results in infinity. Wouldn't a ToE result in the same?

Thanks. Is it possible for you to name a few of these "charlatans" so we can stir clear from them?
Quantum mysticism is a set of metaphysical beliefs and associated practices that seek to relate consciousness, intelligence, spirituality, or mystical world-views to the ideas of quantum mechanics and its interpretations.[1][2][3][4][5][6] Quantum mysticism is considered by most scientists and philosophers to be pseudoscience[7][8][9] or quackery.[10][11][12]
The idea that "observer" means "conscious observer" is more woo.
How about Conciousness in the context of the Observer Effect in QM? The act of observing a phenomenon changes that phenomenon. Is this just a fundamental question of the instrument we're using to measure or observe it? Do we have to observe the observer ad nauseam or measure the act of measuring ad infinitum to get a better understanding of it? How can we measure something that we don't understand or doesn't even know that exist? By accident?
We can't explain the smoke patterns coming from the end of a cigarette, but nobody thinks that they are operating outside of our laws of physics just because we can't explain them or predict them. That is seen as a very complicated emergent behavior from the known laws of physics which is difficult to model, and while consciousness is undoubtedly even more complicated, it's usually seen in a similar light by mainstream science as likely something which emerges from the known laws of physics in ways we can't yet explain or model.
We can't side-step Consciousness' philosophical implications, "philosophical" meaning- relating or devoted to the study of the fundamental nature of knowledge, reality, and existence... which in the end is what science is all about.
Yes and no. As George Box said, all models are wrong, some are useful. When he says they are wrong he is referring to almost exactly what is in the source you cited about them being approximations of reality but always deviating from reality because they are not reality itself.

Sure it's an approximation, but is it a good enough approximation to be useful? That's what counts.
Even if some unification model was discovered, wouldn't it still be an approximation? There's nothing exact in this universe to work with.
We don't know the answer before we have the answer so it's hard to say, but a common thought among scientists is that physics laws are generally believed to be unreliable when they invoke infinity, and therefore the unified model we hope would provide a solution of the black hole which doesn't invoke an infinity, or at least not one which can't be renormalized.
The singularity of a black hole is infinity. Any calculation which includes infinity results in infinity. Wouldn't a ToE result in the same?
The appearance of singularities in general relativity is commonly perceived as signaling the breakdown of the theory.[75] This breakdown, however, is expected; it occurs in a situation where quantum effects should describe these actions, due to the extremely high density and therefore particle interactions. To date, it has not been possible to combine quantum and gravitational effects into a single theory, although there exist attempts to formulate such a theory of quantum gravity. It is generally expected that such a theory will not feature any singularities.
