You can use the Placement.info file for that. I would send you a link to the docs on this, but I think that's currently being migrated or something.
So let me quickly give you the gist using an example:
Basically you're instructing Orchard to not render the shape called "Parts_Facebook_Shape" when being displayed for the "Summary" display type (note that I'm using a sample shape name; I don't know what the actual shape name is that you're using).
The "-" value causes the shape to be hidden.
