I don't see a way to do what you want on a global basis.
I only see one way to approach your wish.
This is through use of the option to / not to export private facts.
You can privatize all instances of a fact (but only one Fact at a time) at:
Edit > Manage Facts > Choose a Fact > Data Options > Select All > Privatize.
Then select not to export private facts.
Then reverse the procedure to make them "public" again.
Other than that, you might explore the internet for gedcom utilities that might remove facts; or post queries to other software boards to see if there is another software out there that will do this.
