API Server applications - portal only

Is it possible to disable certain API projects for a given API Server?

I.e. we want to have a server only running the ApiServer/html/qer-app-portal page, but not running any of the other pages, such as the admin portal, opsupport, and password reset

Web Server1 - running qer-app-portal only

Web Server2 - running all web applications

Reason being we don't want the users to accidentally stumble upon the landing page and the API documentation by removing the /html/qer-app-portal portion of the URL
