How to disable/uncheck Glossiness in multiple content browser materials

How can I disable/uncheck Glossiness in multiple content browser materials? Looking a making a blueprint/widget, but cannot figure out the steps to set the glossiness of a material asset. Seams like it should be simple, but cannot find anything on it. Is there an existing utility that does this? Also want to disable Bumpmap, RefractionIndex, and IsMetal.
