Hi Troy,
Are you talking about the report generation toolkit libraries? We have a few KnowledgeBase articles on this:

There is not a way to silence warnings from the build process as far as I know but definitely posting in the TestStand forum would involve more people with TestStand experience and might result in a better solution for you.
With warm regards,
