How to set maximum expanded height in android support design bottom sheet?

Question

I already showed my bottom sheet layout with its peek height set to 100dp. But how can I limit my bottom sheet to expand to 500dp only? This is my sample layout:

If using BottomSheetDialogFragment:

In my case I was using BottomSheetDialogFragment and modified the bottom sheet peek height by getting its reference by override OnCreateDialog method inside my BottomSheetFragment

@NonNull @Override
public Dialog onCreateDialog(Bundle savedInstanceState) {

    dialog = (BottomSheetDialog) super.onCreateDialog(savedInstanceState);

    dialog.setOnShowListener(new DialogInterface.OnShowListener() {
        @Override
        public void onShow(DialogInterface dialog) {
            BottomSheetDialog bottom_dialog = (BottomSheetDialog) dialog;

            FrameLayout bottomSheet = (FrameLayout) bottom_dialog.findViewById(com.google.android.material.R.id.design_bottom_sheet);
            assert bottomSheet != null;
            //BottomSheetBehavior.from(bottomSheet).setState(BottomSheetBehavior.STATE_EXPANDED);
            DisplayMetrics displayMetrics = requireActivity().getResources().getDisplayMetrics();
            int height = displayMetrics.heightPixels;
            int maxHeight = (int) (height*0.80);
            BottomSheetBehavior.from(bottomSheet).setPeekHeight(maxHeight);
        }
    });

    return dialog;
}
