Collision Deform modifier- body physics

Is there a way to avoid the arms intercepting with the rest of the body? I wanted some kind of morph to happen on the objects.
How I can obtain the result represented on the second image using Unity?
I'm not even sure how to search for it online.
I find it kind of odd that no one has this problem. The animation was done by motion capture so some parts of the body collide and enter inside each other.
