Unfortunately Apple does not train their service techs to read Kernel Panic reports or to do any independent testing other than running diagnostics which rarely detect problems.

Test the clean install to see if you still receive any Kernel Panics which would indicate a hardware issue (test before installing any third party apps & before restoring from a backup). If the diagnostics don't report any issues, then It will really help your case with Apple if you would perform a clean install of macOS onto this laptop which involves erasing the drive followed by installing macOS.

You can try running the consumer version of the Apple Diagnostics to see if any hardware issues are detected. Hopefully with all those Kernel Panics the Apple service diagnostics will show a problem so that Apple will replace the Logic Board. Unfortunately the health report for Apple SSD's is very sparse.

I'm just curious if the SSD's health report shows anything of interest. Just out of curiosity, try running DriveDx and posting the complete text report here using the 'Additional Text' icon which looks like a piece of paper. Make sure you have a good backup while you can since if I'm correct, then the Logic Board could fail at any time. You can try running the Apple Diagnostics to see if any hardware issues are detected, but it rarely detects problems especially ones like you are describing, but it never hurts to try it. I've been seeing a lot of Logic Board failures on my organizations T2 Mac (most have been with the 2019 models). My guess is the Logic Board is bad and will need to be replaced. You can try running the third party app EtreCheck and posting it here to see if there are any more clues. The panic mentions 'ANS2' which stands for 'Apple NAND Storage version 2'. I see this a lot with SSD failures, but hard to know if that is the case here. Since the issue appears during power on or waking from sleep, it seems like the hardware is not powering on properly. This should not affect the data on the internal SSD, but I highly recommend you make sure you have a good backup anyway just to be safe. You can try a DFU firmware ' Revive' to see if that makes any difference. That is an odd Kernel Panic which is referencing BridgeOS which is the special OS used by the T2 security chip.
