In the manga, Roshi used something similar to the UI (it wasn't the UI, but as I said, it was something really similar so I'll call it "Fake Ultra Instinct") while fighting against Jiren, who was holding back and then he started to get serious and defeated Roshi with one hit (The only reason I think this makes sense is that Jiren decided to have a fight to see who is a better martial artist, he didn't use his full power because that could kill Roshi and similar to Superman, he won't kill his opponent)
