Rockpi 4C + Android

I made a try of all distro and all images stored here. I don’t want to abandon the project: Running Rockpi 4C with a Display Port Monitor and a bluetooth headset!!!
It is not impossible to run it with these options with Armbian and all, I repeat ALL 5.xx kernels.
If the Display is ok the Bluetooth not.
To run ALL, I repeat, ALL hardware provided in this SBC It is necessarily the Android 10 image that supports DP and Bluetooth toghether.
But: where is an Androis Wiki page to get some suggestion? As Root user etc etc etc? Thanks.
