To avoid confusion of those who may notice this thread in search engine 
results:

In Debian GRUB_DISTRIBUTOR value is *not* passed to "grub-install 
--bootloader-id" by postinst package scripts:
<https://sources.debian.org/src/grub2/2.12-5/debian/postinst.in/?hl=723#L723>
<https://sources.debian.org/src/shim-signed/1.44/debian/shim-signed.postinst/?hl=64#L64>

that was added to prevent a secure boot issue.

Behavior of SUSE may be different.

I believe, a robust way would be to add grub-install option that reports 
path withing EFI partition configured at compile time, so heuristics 
based on GRUB_DISTRIBUTOR from /etc/default/grub would not confuse users.

*Signed* grub*.efi reads its config from EFI/debian/grub.cfg (that loads 
/boot/grub/grub.cfg) that is fixed when the binary is signed.
