This sounds like you put /boot/efi on the same filesystem as /boot which
is not recommended or supported at all[1].  On my laptop there is only a
single file under /boot/efi, namely /boot/efi/EFI/debian/grubx64.efi -
which will be written to on updates to the grub-efi package, but not
when installing a new kernel or rebuilding an initramfs.
