Installing macOS on a partition.

I'm currently running Niresh macOS Mojave. I have a lot of problems with it. Audio isn't working, iGPU isn't working. So I decided to do a clean Vanilla Catalina installation. My question is if I make a partition in APFS and install catalina in that partition [is it possible?] , can I access files from the mojave partition in catalina?
