Without EFI variables, only the removable media path can be used.
If U-Boot loads GRUB from the EFI partition removable media path, it

That is the case.

None of those files get updated when upgrading to grub 2.14 and doing
grub-install.
It should be updated
automatically if grub2/force_efi_extra_removable is set to 'false' in
debconf. You can check with
debconf-show grub-efi-arm64
$ debconf-show grub-efi-arm64
grub2/force_efi_extra_removable: false
grub2/linux_cmdline:
grub2/kfreebsd_cmdline:
grub2/kfreebsd_cmdline_default: quiet
grub2/linux_cmdline_default: quiet
grub2/update_nvram: true
grub2/enable_os_prober: false
btw, this is a debian live arm64 image that Roland Clobus helped me
build on Mini Debconf Hamburg.
In addition, this system does not seem to use the monolithic signed
image (grub-efi-arm64-signed) which does not need external modules and
would avoid the module version mismatch (but if is not updated in the
boot location then the old version will still be used).
Is the non-monolithic version still supported? Do you recommend
migrating to the monolithic version?
