Keeping characters away from environmental assets

I'm having an issue in a game I'm working on.

there are specific things that I don't want the enemies to run into, specifically just small environmental assets.

Does anyone know of any way to keep the enemies from bumping into them entirely? Or, a way to use the distance attribute to tell them to change direction when they get too close?

Thanks everyone!

I usually do a disable collision action when enemy collides (or overlaps) with the object. This will mean the enemy just passes through it. This would also work for changing direction on colliding with the object.
