Not a clue ... where I live a car port would disappear to Norway in the first big blow 🙂 ..... but might you get away with good quality tarpaulins laced to the structure to make 'walls' ..... on the grounds that it's not a permanent change to the structure?? .... would keep a lot of the wind out and make life easier for your car covers. Would also depend on your tolerance for compromised aesthetics.
