Yes. Regular Norway rats can definitely be potty trained.
If you keep moving their poo to a designated side or litter pan, they will catch on and start using the bathroom in that one spot. And when you change bedding/litter, make sure to leave some of the soiled bedding behind in your chosen potty spot. You can stop the last step once you're sure they understand.
I've successfully trained rats to use a litter pan. Litter training is fairly common among fancy rat breeders and owners.
