How Do You Remove Collision On A Specific Part Of A Static Mesh?

How would i go about removing the collision on a door way on a house (static mesh) that i have? the collision i have set is “use complex collision as simple” that works perfectly for the actual house, but the door way originally had an unmovable door in it, so i transparented the door and am stuck with its collisions, is there any way to subtract collision on a specific area??? THANKS!!!
