Screen rotation on the displaylink displayers is not working though the 2 displays are driving 2x2K monitors fine in landscape mode. I have a Mac Mini M1 with 1.3 driver in Big Sur via 4URPC Triple 4K Display USB-C Docking Station DS-C02 (with 1 HDMI alt port, 1 HDMI Displaylink output, and 1 Displayport Displaylink output) . I have 1x43" 4K monitor and 2x24" Dells at 1920x1080 in vertical portrait mode. The 2 Dells are on the Displaylink output and neither can rotate. And if I mix the USBC alt port HDMI output with the DisplayLink output (either one), the system crashes, kicks me out of the system, reboots, and a minute later, I am back to the initial boot log in screen. After logging back in, my system tells me the DisplayLink manager is disable and manually running Displaylink manager yields nothing (which tells me Big Sur disabled the software because of the repeated crahses). I can re-able the Displaylink manager if I unplug the dock's USBC connection to the mini and reset its power.
