If your issue is the animation, you could try invalidating the FAB Behavior. As for the visibility, you should null the anchor you have set in your layout:

CoordinatorLayout.LayoutParams p = (CoordinatorLayout.LayoutParams) fab.getLayoutParams();
p.setBehavior(null); //should disable default animations
p.setAnchorId(View.NO_ID); //should let you set visibility
fab.setLayoutParams(p);
fab.setVisibility(View.GONE); // View.INVISIBLE might also be worth trying


//to bring things back to normal state
CoordinatorLayout.LayoutParams p = (CoordinatorLayout.LayoutParams) fab.getLayoutParams();
p.setBehavior(new FloatingActionButton.Behavior());
p.setAnchorId(R.id.appbar);
fab.setLayoutParams(p);
