@paulywill@mstdn.ca they can.. of course. But you need to unlock the bootloader to do that.. and you can't do that while its locked :( That's the entire issue..

@codemonkeymike@fosstodon.org @paulywill@mstdn.ca What exactly keeps the bootloader locked ? If its a password or a config, or anything that is runtime change-able, it is then kept alive by the onboard battery. So cutting off ALL available power should hard reset the thing. The only way around this is if Apple hard coded the lock/password/whatever on a silicon level.

@codemonkeymike I am interested to see if you have tried this method https://mrmacintosh.com/how-to-restore-bridgeos-on-a-t2-mac-how-to-put-a-mac-into-dfu-mode/ And https://mrmacintosh.com/how-to-remove-mac-firmware-password-new-way-if-you-have-a-2018-2020-t2-mac/ You need a second Mac that works and you control the one with a firmware lock using Apple Configurator. I have converted Apple Macs to run Linux but all of them have been 2017 or earlier.
