Android custom HDMI Display resolution 480 x 480 on 4B+ OP1

Hi,

I´m planning on using the RockPi4B+ OP1 with a 2.1" round HDMI Touch Display and an Android image (preferably Android 7).
Display resolution is 480 x 480.

Does this work plug&play with maybe cropped desktop? Would be fine as I use my own fullscreen app.
Do I have to compile a custom kernel/image?

Thanks and best regards!
