Permanently Disable Plex Relay?

Does anyone know of a way to permanently disable Plex Relay? Currently I have to rename the PlexRelay executable in order to disable it but after each update it gets recreated.

Here is a possible solution.

I have not tried this yet so I don’t know how well it works but I am curious to know.

I just found this thread which seems to be the best solution that exists at this time.
