Procedure to flash Jetson tx2 with Auvidea J140

I’m looking for the procedure to flash auvidea driver with jetpack 4.2.1 or 4.2.2.
I don’t find a written procedure for that. Can someone help me on this?

I can’t give details, but the device tree, and perhaps a few other parts, need to be edited for their carrier board. Basically, the NVIDIA flash software could be used, but only after adding the Auvidea content. Somewhere on their website Auvidea will have a board support package, and this is basically just the default software after adding other support, e.g., device tree changes.
