If you want to remove bloat, you can use this software. It doesn’t require root. Just be careful to not disable important system apps otherwise you can make your tablet unusable and will have to find a way to go to recovery and factory reset.

I used it on a friend’s cheap Chinese phone and it removed a lot of stuff. The phone was much better after that, but of course, be extra careful to not remove important stuff.

Good luck!
