Preventing users from changing a repository's visibility
You can prevent members from changing the visibility of organization-owned repositories on your GitHub Enterprise Server appliance.
When you prevent members from changing repository visibility, only site administrators have the ability to make public repositories private or make private repositories public.
If a site administrator has restricted repository creation to organization owners only, then members will not be able to change repository visibility. If a site administrator has restricted member repository creation to private repositories only, then members will only be able to change repositories from public to private. For more information, see "Restricting repository creation in your instance."
