Customize Android Projector UI?

[Jellyfishpudding]

Greetings! I just purchased the XNANO X1, a budget projector that has been rebranded a few times I'm sure. It's running Android 9 and has an interface that looks horribly dated. I was wondering what success I might have in updating it. Not sure if there are launchers that might do the job or whether I can simply replace images via the file browser. I'm only assuming that I can gain access by connecting it to my desktop. Any insight would be greatly appreciated.
