Unity Preview Without Launching Rift?

My Rift is connected to my PC so that hitting the Play button in Unity always launches the Oculus application and uses the Rift's position for the camera. I'm new to Unity and am testing out physics scripts and don't need the headset to run every time I hit the play button. I have tried unchecking the OVRPlayerController, deleting the OVRPlayerController GameObject from my hierarchy, but it seems that if Project Settings > XR Settings has Oculus then it will still auto-launch on the Rift. Is there a method to not do that and instead use the standard Unity preview within the same project?
