Any way to square off tilemap colliders?

I have a tile map which its surface isn't smooth it has foliage and jagged edges on the walking surface. When I generate a tilemap collider with a composite collider the collider is jagged and matching the surface. Is there a way to square this off rather then be so precise?

Edit : Figured it out, Vertex distance on the composite collider will achieve this.
