No way there is a schism. Why? There is no game mechanic to do it.
No one wants to the be ones having to essentially start from scratch for their schism-ed religion.
And if they did try, it would be incredibly hard to do and they would likely just fail hard and be destroyed.
There's a simple game mechanic. You leave the current religion and found a new one based on it.
Last time there was a schism it lasted for some time and only failed because Allison alienated herself from the host nation. The church really didn't do anything. The Prophet declared it evil mostly because Allison failed to come up with any legitimate religious basis for the faith. You could probably house an SA schism in Asylon, Libero or a southern realm quite easily. Remember several realms still have religious freedom.
