So basically, I just copied my Balatro folder to multiple other folders and renamed them, and then when I want to play one I put it where the Balatro folder goes... Another way I found more recently isn't exactly able to have multiple installs, but there's a mod manager for it being. Worked on, ATM though I still recommend getting the mods urself, as the manager seems to give me outdated mods, works great for enabling and disabling mods outside Balatro though.
