XPS 13 Plus 9320, USB-C issues

Question

XPS 13 Plus 9320 slow charges on a USB-C device with passthrough and won't see a USB-C monitor. When I connect the power through my Anker dock, the BIOS and Windows presents a warning for Slow charge, and when I connect a USB-C monitor (Iiyama) in the office, it does not work. Windows 11 pops a message saying that the DisplayPort may not be compatible. I've tried all other laptops variant - Precisions, Latitudes and older XPS's and they all work fine. I've run the SupportAssist and updates all recommended drivers and BIOS feature but it makes no difference. Any advice/thoughts?

Same issue here with my brand new XPS 9320 and a iiyama prolite XUB2492HSC

The new dell can connect to other screen via a lenovo dock station, my old MSI can connect to the iiyama monitor by the same usb-c cable. But the new XPS cannot use the iiyama, and I really need to fix this
