Hi, Is check_signatures=enforce <https://www.gnu.org/software/grub/manual/grub/grub.html#check_005fsignatures> currently only supported on EFI platforms?
I see this question has been asked before <https://lists.gnu.org/archive/html/help-grub/2019-12/msg00006.html> but there was no response. Regards, Hanson
