 public void Awake() {
          StartCoroutine(SwitchToVR(()=>{
                Debug.Log("Switched to VR Mode");
          }));

          //For disable VR Mode
          XRSettings.enabled = false;
  }
 
  IEnumerator SwitchToVR(Action callback) {
            // Device names are lowercase, as returned by `XRSettings.supportedDevices`.
            // Google original, makes you specify
            // string desiredDevice = "daydream"; // Or "cardboard".
            // XRSettings.LoadDeviceByName(desiredDevice);
            // this is slightly better;
            
            string[] Devices = new string[] { "daydream", "cardboard" };
             XRSettings.LoadDeviceByName(Devices);
      
            // Must wait one frame after calling `XRSettings.LoadDeviceByName()`.
            yield return null;
          
            // Now it's ok to enable VR mode.
            XRSettings.enabled = true;
            callback.Invoke();
   }
