UL 2-hr FFR assemblies for open webbed steel trusses ceiling/floor

This is a shot in the dark as I know we’re not always ready to provide technical advice in this sub. I have been searching for eons and trying to find a floor assembly for a steel truss (not c-shaped joist) that meets 2 hours. Perhaps they need serious blocking because of the open nature of the trusses? Not wanting to create a smoke baffle?

Any insight would be GREATLY appreciated!
