Comment # 3 on bug 1182839 from Lukas Ocilka

It works this way:

See
https://github.com/yast/yast-bootloader/blob/1e9710254b9be420c4c6dab76ade2cf5d112aa1e/SUPPORTED_SCENARIOS.md#grub2-efi

## grub2-efi

This option requires packages based on the architecture of the system:

- i386 architecture requires: grub2-i386-efi.
- x86_64 architecture requires: grub2-x86_64-efi. If secure boot is used, it
also - requires shim and mokutil.
- arm architecture requires: grub2-arm-efi.
- aarch64 architecture requires: grub2-arm64-efi.

Here's the code:

And here's a test:
