Boot Android into HDMI IN mode, rather than launcher

Which system do you use? Android, Ubuntu, OOWOW or others?

Android 11

Which version of system do you use? Khadas official images, self built images, or others?

Self build with no modifications

Please describe your issue below:

Is it possible to make Android default to HDMI input at boot time - rather than the launcher? So, instead of having to pick settings → khadas settings → HDMI IN, the input is automatically selected?

I’m new to Android so any clues would be appreciated!
