Adjusting front wing angle is standard practice during stops - they’ll certainly do it when they change tyre compound (eg from softer to harder tyres), and they do it quite often otherwise.
They have specialised tools to do it too!

Interesting. I had no idea, I suppose because everything happens so fast during those stops. (the ones that do not involve replacing the wing wholesale, which does take a few seconds.) Of course it makes sense that a different tire compound might benefit from a different amount of downforce.
