You are going to fuck this up. Don't come crawling back to me when you lose all your data since the dawn of time and you completely brick this goddamn computer. This is your one and only warning.

    Efi spec states it must be safe to delete all variables. It's only motherboards not adhering to the spec that are affected, effectively faulty hardware.
    If you do this on a mb from that era chances are nothing will happen, and if something does happen chances are it is recoverable. You'd have to have some truly bad luck on your choice of mb to have it be permanently bricked by that.

    Yes, but many modern mainboards do feature two UEFI copies and can switch to the backup on the fly - and most let you restore a bricked UEFI from a USB drive. Not sure if this can help here or even work on this situation, but it might be worth a try.
