Have a question about disability premium

Hi there I done a lot of reading and what I can gather is the serve disablity premium has mostly been replaced by UC. I was wondering if any of the disablity premiums are still possible to get if you're on unversial credit as well or not. I've also got the enchanced version of pip so was wondering if I'd be entitled to any of those other benefits? Or if there any other support I can possibly get. Thank you!
