Forcing Primary Group and Account Flair suggestion

One of our clients runs a large community with Discourse where every user can see the user’s “Status” which is represented by Group & Flair. While we’d like the users to keep their flairs and for everybody to see “who is who”, Discourse allows users choosing Primary group and Flair.

Is it possible to globally force users to have their Primary Group Title unchangeable and disabling Flair selection? Any manual manipulations are out of scope here due to popularity of the forum and we’re talking about dozens of thousands of users in some groups.
