Yes.
He self-published a lot of material under various pseudonyms / sponsored others to write biographies that painted him as a Tony Stark adjacent character. A lot of Iron Man comics are based on exaggerated version of Feynman stories.
He was a truly brilliant "top 100 of all time" type physicist, but also had one of the biggest ego's I've ever looked into. Pair it with the misogyny, abuse of power, racism, etc... I'm not his biggest fan.
E: Why is my original comment being downvoted/flagged lmao. This site is odd sometimes.
He certainly gave interviews to people who'd then write biographies pseudonymously under Fenymans own name, but I'm not aware of any autobiographical stuff he wrote. What are some works he self-published pseudonymously?
