Disable the creation of Initial work items

Yes this is possible. The creation of the initial work items are performed by a project creation follow-up action. If you open the project area editor and switch to the "Process Configuration" page, then in the Configuration tree expand to the "Project Configuration > Project Area Initialization" you'll see in the right a server follow-up action called "Setup Project". This creates streams and work items. You can customize it or update the template you use so that new projects have a different initialization behavior.
