As the title says, is it possible to turn off "Colonial Nations"? I am colonizing North America as Zhou at the moment but then an event popped up saying there was a new colonial nation in California and took all my North American colonies. Is there any way I can re-incorporate the colonial nation back into my empire or to turn off this event altogether? I don't mind if theres an option to release the colonial nation as a vassal or if rebels spawn and form one, but I hate how it forms automatically. 
Also the wiki here says I need to buy the "Conquest of Paradise" DLC to have Colonial Nations but I haven't even bought it yet.
