There’s no way to delete or modify your listening history on Apple Music, and thus no way to get rid of unwanted recommendations AFAIK. At least with Spotify you can just create a new account, but your Apple Music account is tied to your appleid, so that’s not really feasible if you’re a heavy Apple user. I just try to find the service with mostly the same features but with the least intrusive recommendations and use that, which at the moment is Qobuz.
