How to remove Blender "useless" bones with "bone" parenting?

Maybe, but when I try to parent like this, but with Armature Deform everything works fine, except it deforms! I need a way (if possible) to remove those bones from UE4 AND achieve the same non-deform effect on all of the meshes. When I select Armature Deform, my meshes deform really weirdly, and the best way for me is not to deform at all. You said about skinned mesh, what is it and will it help me do effect I described?
