Yeah, it's a mess with EFI. I wrote this in November 2020:

    "Redundancy for EFI System Partition: what do people do in
    2020?"
    https://lists.debian.org/debian-user/2020/11/msg00455.html

    (worth reading replies for more authoritative answers relating
    to Debian)

and as far as I am aware the situation is still the same, i.e. a
choice between a couple of unsatisfactory options.

I still have two independent EFI SPs and mirror them at every grub
package update.

Cheers,
Andy
