Kasparov also believes this to be true, but the last example I can recall of top level player teaming up with a computer was in 2014, when Nakamura played exhibition match with engine against Stockfish and lost 1.5/0.5, since then computers only got better. Maybe someone dedicated to playing computers could perform better, but I doubt it, since anti-computer chess haven't really been a thing outside of bullet and maybe blitz for years, now that computers search way deeper and prune better.
