You cannot. Yes, some wikis do have forums and Discussions, such as one of mine because I had requested Discussions to be enabled before they were forced on their own from forums to just Discussions. Once they are fully migrated, there's no going back.

But any newly created wikis will have Discussions and only Discussions.
