Fillers for Morphea?

Hi, I was diagnose with linear morphea a few years ago. I have an indentation in the chin area that I would like to improve. I know that fat grafting is an option but looking for something less invasive. I would like to try filers but was wondering if doing a subcision in the chin area before putting fillers would improve the cosmetic outcome ? Or could it trigger the morphea to become active again ?
