is it possible to affect bones on skineed mesh by wind?

If you are referring to Unity wind, you probably need to animate your armature to make it look like it is affected by wind. You probably need to give more information to your question, because there are a lot of different things you can do according to what you want to be affected by the wind.

If you want to move the bones of something that’s animating, use LateUpdate(). I have no idea what you mean by “automatically” animate, that’s not a thing.

If you’re talking about Wind Zones, they only affect trees. If you want wind to affect rigidbodies or anything else, you need to script it.
