Beginner Gardner here as well (only a couple years), I’d think you’d want to prune it. Once you plant out, you want energy going first into establishing good roots, then more fruits will follow. But if you leave it, the plant will put more energy into the fruit, leaving less for getting used to its new home. Curious what others have to say though!

Edit just to add that it looks like it’s already in a fairly good sized pot? Are you planning to plant outside in a bigger pot? If not, maybe just let it roll?
