You found nothing in Google because this is a Windows tablet and Android was never made available for it. The best you can do is to exchange the tablet you have for the V919 Air Dual Boot, an older tablet with Windows 8.1 and Android 4.4 on board. An alternative is to install the latest build of Android x86 on the tablet you do have, but there is no guarantee any of your hardware will be properly supported. Also, while not a huge deal for a tablet, Android x86 currently is based off Android 8.1 and always tends to run a few years behind Google.
So is there some reason you cannot use Windows 10 on your tablet?
