You don't need to boot a whole OS for that, you just need to boot a stub that could work entirely on USB I/O (basically treating it like a serial port) if you can't even figure out how to get the GPU to output text.

I'll bet the efforts to boot Linux on the M1 have already progressed to the stage where they could run memtest.
