There is no EFI on Apple Silicon. It's a more iOS-ish pre-boot environment (based around iBoot and some other Apple-y things).
There's also not exactly a boot picker in firmware-- that lives in the recovery OS. Which will also be unbootable if you're impacted by this issue because it's a minimal macOS environment; if your only OS is 13.6/13.6.1, that recovery partition will also be 13.6/13.6.1, and, if you have upgraded to 14.0/14.1, that installer can fail to update the recovery partition and leave it at 13.x (whatever you were on when you upgraded).
