Firestop sealant is commonly used to seal holes in wooden framing with NM running through them.If you can find a spray foam that won't harm the conductor insulation I would clean out the weatherhead and use that.
I would unsnap that cover and clean it out first. I would also stick something in the raceway to keep it from filling up with foam.Make sure to wait until any hatchlings have left.
