You can restrict who has the ability to change the visibility of repositories in your organization, such as changing a repository from private to public. For more information about repository visibility, see About repositories.
Restricting who has the ability to change the visibility of repositories in your organization helps prevent sensitive information from being exposed. For more information, see Best practices for preventing data leaks in your organization.
You can restrict the ability to change repository visibility to organization owners only, or you can allow anyone with admin access to a repository to change visibility.
Warning
If this setting is enabled, individuals or GitHub Apps with admin access can modify the visibility of an existing repository even if the ability to create a repository with that specific visibility has been disabled. For more information about restricting the visibility of repositories during creation, see Restricting repository creation in your organization.
