Disable terrain EnableTreeColliders in script

I have an open world game with a large number of terrain tiles and an editor script to manage all of them. I'm trying to access TerrainCollider > EnableTreeColliders in my terrain manager script to turn it off (it's on by defautl) in all of my terrains because I don't need it and it's causing some glitches, but I haven't found a way to reference it in code. I need colliders on my terrain trees, I just don't want TerrainCollider to mark them as terrain so I need to turn EnableTreeColliders off. Any ideas?
