There is a way to hack this, which is undocumented and not a blessed way of doing it, but should work
In the registry go under:
HKLM\Software\DisplayLink\PIDS\0100XXXX\Branding (where XXXX is the USB product ID of your device connected)
And change the "UIGroupingName" to an empty string.
Restart the DisplayLink Manager service and the UI should have disappeared for that PID.
