grub-mod-setup_var: a modified GRUB allowing tweaking hidden BIOS settings

There is a fork of GRUB that lets BIOS modders access the BIOS using “CFG Lock”.

I didn’t know about “CFG Lock” before today; it appears common knowledge in the modding community. Does CHIPSEC check for this? If not, should it?

There’s another Github project, documentation-only guide for some Insyde BIOS users, which relies on this GRUB fork.

Little guide on how to show all the settings in clevo insyde_h20 uefi.
