BottomSheetDialogFragment - Allow scrolling child

Question

I have a BottomSheetDialogFragment with a RecyclerView. The problem is, I want to disable the drag close function of the BottomSheetDialogFragment as long as the RecyclerView is not scrolled up (currently I can't scroll my RecyclerView as the attempt will always close the BottomSheetDialogFragment). Any ideas how to achieve this?
