I’ll be frank. I’m looking to install another ROM/Distro of Android onto a tablet.
It’s just a basic tablet running a stock version of the Android OS. The tablet is a knock-off they don’t sell anymore on Amazon; but I know it has Google services installed everywhere on the thing. I’m looking to a method or means to de-google the thing and asked around which lead me here.
Has there been an attempt to create an Android Tablet version for this OS? Mostly for just a basic tablet.
… so this would be the information to use to search for devs working on the device. Trying XDA https://xdaforums.com/search/72470784/?q=Fancy+Day+C10&o=relevance I find no hits, but you could keep looking. Allwinner have said that they publish sources openly but actually some blobs are held back; off topic for here but you might find the tablet partially supported by Linux.
So your best bet for /e/OS is as said by @piero, GSI.
