I know I'll regret getting in on this but...
Much of F-35 supersonic testing and training happens over the ocean and in the R-2508 supersonic corridor on the Edwards AFB range, (412th Test
Wing). Due to noise pollution supersonic activity is prohibited below 30k ft. which is why there are no low pass photos, vids or other accounts.
That said, 58% of the over land flight tests for the F-35 are held around 30k ft. generally meaning supersonic flight tests.
Here is a written account of supersonic flight in an F-35A:

"For example, many data points require supersonic flight. The High Altitude Supersonic Corridor in the R-2508 Airspace is only 240 miles long. At 1.7
Mach, that's still pretty cramped; so we use the sea test range instead. Right now, there is a lot of this testing going on with the F-35 Joint Strike
Fighter,"
