Need help updating a rkpx6 android head unit from android 9 to 10 or 11

[Conald P.]

Hey guys got a rkpx6 vertical head unit running android 9.0. I was wondering if there is anyways to upgrade the android version to a newer version such as 10 or 11. All I can find is 100$ firmware they try to sell you that adds "themes" doesn't update anything really regarding Android.

Here's some pictures with device/software information:

There is for now no way to get Android 10 onto these units.

...and by the way. Reminder only the next day.
