AFAICT, it is there for use by systemd-boot and possibly other alternatives to
grub-efi. I'm not sure of the source, but it could possibly have been from
having
installed the usrmerge package.

I don't like seeing it in / directory lists, so obfuscate it by removal and
replacement by an empty immutable regular file by that name.

AFAICT, if you are already UEFI booting via Debian's grub-efi-amd64, you already
have all you need. Simply
grub-install
sets up the UEFI BIOS and the required file(s) on the ESP filesystem. Whether
grub
itself is fully and properly installed and menuing or not, if your UEFI BIOS BBS
hotkey presents an entry described as UEFI debian, it should successfully boot
your Debian installation. If you will have multiple Debian installations in the
same computer, I recommend editing /etc/default/grub and giving
GRUB_DISTRIBUTOR=
a unique string value, e.g. "trixie-p03n", to give each a unique ESP entry, thus
keeping each from overwriting any other(s). This is best done and applied
/prior/
to any second or subsequent installation.
