How to reduce animation/flexing deformity (but still have unders)? Would tear drop, instead of round, reduce it?

Would dual plane 3 reduce it (compared w fully under)? Would reducing the strength of my chest muscles, by doing less chest weights, reduce it? Or would fat grafting to my cleavage hide it? Other ideas? (I understand I can't eliminate it with unders, just looking to minimise it!) Thank you!
