Android 10 on ROCK PI N10

In the downloads page of ROCK PI N10, only Android 8.1 image is available. Does it mean that Android 10 is not supported on ROCK PI N10?
Also, I would like to know if it is possible to flash Android 10 image (from ROCK PI 4 downloads) on N10 eMMC?
Any help would be much appreciated. Thank you.
