In a properly implemented EFI, this should be possible. But there have been cases with improperly implemented EFI in some laptops/motherboards where the computer won’t POST anymore after /sys/firmware/efi/efivars/ was nuked. In that case, accessing BIOS or booting from a flashdrive isn’t possible anymore.
Why would it be a permanent brick? Shouldn’t a flashdrive and access to BIOS be enough to get your PC working again?

Bro, BIOS is located on motherboard and EFI variables only needed to boot an OS.
Just install bootloader and OS in drive
Bro, several people bricked their pc that way. I’m no expert, just throwing out a warning not to do dumb shit.
I have a little flash chip reader and backed up my bios and can flash it on the laptop. Even modified it to unlock the advanced menus Lol
But th rm rf thing didn’t nuke it so I guess I’m safe either way
