The early Sony Alpha A7 cameras run Android (really: you could jailbreak and write your own PlayMemories apps)

So there must have been a way to do this at that time. (I suspect a simpler subsystem does initial boot response).

I did contemplate building something around one of the Arducam modules and an RP2350.

They always ran Linux and Sony ported AOSP userland to it. So it's slightly different to real Android, and those cameras are not always in that mode.
