As far as I know virtually all of the EFI vars will be stored on battery-backed NVRAM, so the usual solution is to just clear that, by removing the CMOS battery. I am pretty sure the only solution are things you definitely can not read or write from the host OS (e.g. BIOS passwords.) Does require partially disassembling the laptop though, and I know there's at least a couple random models of laptop that actually stop working if you clear the NVRAM (lol) |

Not sure how that happened.
