it's not "FIPS hardware", it's your regular hardware with a FIPS flag set in the config. You guys have your own supported command in the bootloader to wipe FIPS mode and any related configs, just run "factory set-default" in the bootloader. If this is supposed to be some huge secret, maybe don't publicly publish the sources that include said commands?
You've added even more ways, looking at your init script that starts under linux, however I will keep those secret as they are not published like factory reset is
