DDM, USB upstream switch

I'm using the U3821DW and control input switching through command line DDM. I can enable PIP mode like this: ddm.exe /SetPxPMode PIP-Small DP USB-C

So far so good, it works great. What I haven't found out however is:

How can I select/switch the USB upstream port using DDM on command line? I'm looking for the same effect as if I select "USB switch" in the monitor OSD.

Thanks!

    It works! Awesome, thank you so much! Dell Support gave me response that it's not possible before

    And in case anyone else is looking for it: I also noticed that the following works as well to switch the video:

    ddm.exe /SwapVideo

    Thanks again!
