Blocking forced win10 Windows Update via Firewall rules (till I want to turn that off) ?

So, I have a metered ISP besides from 12-5 AM (ViaSat-1/Exede).

Is there some specific way I can set the RB951 to block Windows updates till I want to turn that rule off and get them since the updates are forced now for wired connections ?

The only other way I see is to go full on wireless (Which I refuse to do) and set Windows 10 to metered (like I can’t do in Windows 8 either for wired).

Any ideas?
