How to hide controller models?

[Caden]

This might be a dumb question, but I haven't found anything in the documentation on it specifically. 

I assume there's a straight-forward way of showing/hiding the default controller models during runtime? I guess on that same thought process is there a simple way to replace the controller models with something different if desired?

Thanks
