Customizing the environment on a Windows Server

My application uses the WebSocket protocol, which not included in the default Windows Server configuration. Manually i can enable it by setting according item in the Server Manager via Add Roles and Features Wizard (Web Server (IIS) -> Web Server -> Application Development -> Web Socket Protocol).

If I want my app to work, i need connect by RDP and manually check in this option. But it is a terrible approach..

I think this task can be accomplished by deploy setting (.ebextensions)? But how can i get it?

I would be very grateful for the answer!
