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.
