Yeah this is sort of funny because Linux used to let you delete EFI vars, bricking motherboards, since it mounted them to the root filesystem. It’s since been patched in every motherboard, but sometimes full control is more dangerous than “haha I can just reinstall”

Are there not physical ways to reset efi vars? I'm pretty sure there are
There are now. In 2016, there were motherboards that didn’t properly implement the UEFI standard, outlined in the link I provided, and those motherboards would be bricked were someone to delete the EFI vars. The motherboard would never reach POST on boot
Those motherboards have no excuse to do that. I hope people at least got their money back if they were under warranty
Not really bricked, you could always use an external flashing tool, and they are cheap
