How to disable a skeleton's bow without removing its AI or bow

is there a way to stop a skeleton from shooting temporarily (for like a few seconds) without removing its ai or its bow?
I don't want to remove it's ai because that disables gravity for the mob, and I don't want to remove the bow because it will look jank.
I'm trying to add a cool down to how fast skeletons can shoot arrows, and this would make it incredibly easy if it's possible.
