"There is no 4 season rule, but Disney has/had a rule that very show would only have 65 episodes, but it is probably gone."

Shows usually get 3 seasons. Depending on the popularity of the show it could get a fourth season. Such as "Bunk'd" which was cancelled last year and has return for a fourth and final season. There could be a fourth season of Amphibia in the far future but that may be unlikely due to the ratings of views as of now. We are lucky to even have two.
