Rift dk2 - connect without SYNC OUT

Hello. I have 4 Rift Dk2 oculus. All of them without the original Sync Out Cable and without the Position track sensor.

I found that the DK2 works perfectly, using a common HDMI cable and a USB cable, both connected directly to the Computer.

However, the Oculus Software has a critical error, stating that the sensor is not connected and preventing me from using any external platform, such as Steam VR for example. I did a test connecting any sensor to the USB, I used a Rift Cv1 sensor, which is incompatible with the Dk, but incredibly this was enough to allow the use of the HeadSet in Gyroscope mode. This way I managed to use it on Steam VR, exactly as I would like. But I don't want to have to connect a sensor to the USB, I want to eliminate the need for the sensor.

The question is, how do I eliminate this criticism that requires connecting the sensor to the USB? Is there a parameter file that I can change so that the Oculus Software no longer requires the sensor?

Thank you !!
