Some people could not make that version work at all on their system.

Hello, in the last update this morning i updated to kernel 6.4.1-zen2-1-zen and updated grub from core/grub 2:2.06.r566.g857af0e17-1 → 2:2.06.r591.g6425c12cd-1. After the grub-install … and grub-mkconfig -o /boot/grub/grub.cfg i reboot and could not boot in any of the grub menu items. the error message, when i select a kernel to boot, would be: loading snapshot: date @snapshots/snapshot loading kernel: vmlinuz-linux-zen … error: symbol grub_is_shim_lock_enabled not found loading micro…

I see the OP did what was supposed to be done but…
You confirmed my worries when I said:

But still, I (as my own personal thinking) I did not like the idea of a software change that may lead to an ubootable system or require such attention from the user. I just thought how would I be sure that nothing similar will happen again in the future so that the hook might not work!

This is what I was worried about!
I won’t discuss further here so not to be hijacking our friend @arch54 thread.
UPDATE:
I created a new thread at Grub Breakage ... Again!
