The YT9217B is a 7-inch or 10.1-inch head unit built around the or AC8227 chipset. Originally, many shipped with Android 8.1 Go or Android 9 , but some modified firmware versions can display "Android 10" (usually a build.prop edit). A true Android 10 update for this chipset is rare, but many resellers provide a "look-alike" firmware that brings a new UI, dark mode, and performance tweaks.
