Is USB connector manager supported?

I've never dealt with such devices. MS Windows Device manager shows it under "USB Connector managers" category as:
UCM-UCSI ACPI Device.

The box is Dell Precision 7540, it has 2 USB-C and 2 USB-A connectors. There are 2 USB controllers on the motherboard.
So far I discovered, that any USB-3x device plugged in a USB-C is being connected to one controller, everything else - to another controller.

I'd like to have any kind of control on this since I'm passing-through one of those USB controllers to a bhyve guest.

Thanks for advises!
