hi - I've got an Orange Pi  Zero 2 running Debian Bullseye.
The plan is to use it as a headless device, and I want to prevent users to be able to connect it to a monitor.


Is there a way to disable the HDMI?

I've tried to figure out the module to blacklist in /etc/modprobe.d/ or a driver to disable in /sys/devices/platform/display-engine/drm but so far no luck...

appreciate any suggestion
thanks

So glad you posted this question. I'm hoping to do the same. Did you manage to figure it out, @wrossi? Or any good suggestions from the other users?
