In GRUB we have
debian/patches/efivar-check-that-efivarfs-is-writeable.patch
which ensures that if EFI variables exist but are no writable we don't throw an error in grub-install.
Commit 931e97b57b64 ("linux: handle non-ACPI systems in device_get()") in https://github.com/rhinstaller/efivar ensures that EFI variables can be accessed by efibootmgr on non-ACPI systems. Since efivar (37-6ubuntu3) this fix is available in Mantic and Noble.
