There is a way, the Power Delete Suite script can overwrite all your comments with any message you give it, and then follow it up with mass deletion if you wish, only catch is that the original doesn't account for reddits current rate limiting and so misses stuff , but this fork of it seemed to do the trick for me

There is a mobile app(UntrackMe) that does a similar sort of redirecting https://fedilab.app/wiki/untrackme/
