Tankers U-turn, zig-zag, pause around Strait of Hormuz

Iran could enforce selective closing very easily because they can shoot across the strait from the coast. It's a mountainous region where Iran has a bunch of missile installations which would be very difficult to dislodge. Iran can also trivially enforce a full closing because the strait is very shallow. All they'd have to do would be to scuttle a couple of corvettes there, and it would be completely impassible. Full closure would be the nuclear option.

People talking about the effects of closing the straight being bad for multiple countries. Can Iran enforce a sort of selective closing, like the houthis did? Allowing ships as long as they dont trade with the usa? Or maybe only allow countries that dont host usa military bases?
