Advanced users • Reading secure boot keys from the booting OS.

I'm in a situation where I need to verify the Pi4/ Pi5 hardware where my images are running is authorised to run the image or not. One possibility I could think of was reading the customer public key from the OTP and check it while booting to conditionally change the booting behaviour of my images.

However my GoogleFu was unable to find anything about reading the keys from the OTP.

I'll be greatful for links to any documentation related to this capability.
