An organization owner must allow forks of private and internal repositories on the organization level before you can allow or disallow forks for a specific repository. For more information, see "Managing the forking policy for your organization."
- On your enterprise, navigate to the main page of the repository.
- Under your repository name, click Settings. If you cannot see the "Settings" tab, select the dropdown menu, then click Settings.
- Under "Features", select Allow forking.
