So flashing the firmware would “solve” the issue? As in, it should rewrite the variables missing (and everything else), making the hardware usable again?
Generally speaking, these platforms are not flashable unless they can boot a flash utility, assuming that whatever prior firmware is running is at least in good enough shape to boot to an update environment.
There are designs to be robust and accessible even in the face of all this, but relatively rare, effectively unheard of in laptop market. Even some of those emergency recovery environments may be more limited than you would like to repair this sort of thing.
