Any ROMs that work for T377V variant

Search This thread
Hello, I am a newb with regards to the tab E, I have done some minor twrp based work, but years ago, on a different android device.

Question- is there any ROM that I can install (lineageOS, dotOS, etc) to the t377v variant? I just want an OS that stops the tablet from being so slow- I just want to be able to read ebooks , stream videos while operating in an OS that isn't so terribly slow .

I saw a youtube with a guide on how to install dotOS to a Tab e 9.6 after rooting, but noticed it wasn't the t377v variant he was using. I am especially wary, because from what I saw, the t377V seems to be a type where rooting is still not possible (please feel free to correct me here)
