Prevent Angular AuthGuard from redirecting to login form

I followed the basic Angular tutorials for integrating Auth0 and I have run into a snag. I do not want the behavior outlined below:

Protect a route component using the built-in AuthGuard . Visits to this route when unauthenticated will redirect the user to the login page and back to this page after login.

I want the AuthGuard to redirect to a general login page in my application, instead of the Auth0 login form. Is there any way to configure this behavior? I have not found any documentation regarding it.
