Entity First Framework Code: Skip Initial Discovery Model

I used the ignore method to ignore the objects that EF is trying to map to my DB against my will. Doc states:

This is used to remove types from a model that were added by convention at the time the original model was discovered .

Now I find myself doing this for too many objects in my model. Is there a way to tell EF I'm going to manually render the entire model or just skip the initial opening?
