How to enable virtual channel without SERDES(Serializer/Deserializer)

Hello. I have a question about enabling virtual channel not using SERDES(MIPI Directly) in L4T 32.2.1.

I could find IMX390 driver in L4T driver examples but it use two virtual channel to bring up each front and back camera sensor.
Actually, I want to bring up one camera and it needs two virtual channel. And now I’m not using SERDES and made MIPI bridge board to connect jetson xavier.
So Is there a guide or example to bring up virtual channel without SERDES ?
Sorry we don’t have this kind of sample for reference. However I think the key point of the VC should be the device tree define you still can reference to imx390 for the device tree part.
