Hi12 - Android Update

I have a Chuwi Hi12 dual boot tablet with Windows 10 and Android 5.1. Windows automatically updates but the Android O/S is still as originally installed. Is there any way I can update the Android version to something more recent?

The tablet details are CW1520 64bit Hi12 Q64G45170404873

Intel stopped supporting android and there will be no official firmware above 5 android. You can try to install https://www.android-x86.org/ if you really want updates.

Thank you for your reply. I am investigating your solution.
