GPI-Case 2 with raspian bullseye - possible to disable standby

[Gunnar82]

Hi,

i have a gpi case 2 installed with cm4. i installed raserry bullseye.

i created a program written in python3 that i can use the case as mp3 player.

After 15 mins the device disables display and audio if no input.

Is it possible to disable the powersave-feature of the case with kernel overlay or gpio config?

Thanks

Gunnar
