Combining URP and HDRP (PLEASE HELP)

I was wondering how I could make a few scenes URP and others HDRP, for instance, I would have HDRP animations for cutscenes and some gameplay like quick-time events, and for most gameplay, it would be URP. So I was wondering if someone could help me or at least put me down the right path to combining them, or using the built-in scripter for making a custom render pipeline. Could I make my URP project dynamically load HDRP files into the game, or vice versa, I don't know. I need help. PLEASE
