Hi8 Pro CWI513 - Requesting Software/Instructions to switch from Win only to Android only

Hi - I have a Hi8 Pro (PQ32G22151102646) Intel 64-bit Quad Core Z8300 Dual Operating System (Windows/Android). A while back set it to Windows 10 only so no option to go back to Android. With Win 10 no longer being supported by Microsoft and (hopefully) to obtain better performance, I’d like to set it to Android only but no longer see that available on this tablet. Is there software/instructions on how to switch it to Android only?

My understanding is that it will require booting from a USB, but don’t think the tablet is set to boot from USB if inserted so probably need instructions on that too.

Have you checked if you can upgrade to Windows 11 ?

Already having performance issues with Win 10, so going to Win 11 isn’t going to make it better. Thinking for my use Android will be a better option for longer term use.
