Drone with VTX and Cam but no Goggles

So I’m building a drone and I have the VTX and Camera for it but the thing is I don’t have Goggles for the footage right now, so is it possible that I install the VTX and Cam in the drone but not connect them to any Video Receiver/Goggles or should I not install them till I have something to which I can receive the footage?
