I like know, if I can unmake a parent, and not unmake the deformation of the objetc. 
It sounds like you’re using a deformation object. You can apply the deformation to the mesh to make it permanent and then unparent the two. I’ve had limited success making what I was messing with look good because it ended up distored, but I was working on something very detailed. To apply the deformation press SHIFT + CTRL + A.
I believe that does it anyway. Good luck!
