macOS Ventura on Apple Silicon MacBooks requires user approval to allow USB and Thunderbolt communication with the host before it can send data through wired USB-C port. Otherwise, device can be used as charger if power delivery technology is present.
This does not apply to desktop Macs. Those do not have the USB Accessories security system.
By default this protection will require the user to grant access every-time new USB/Thunderbolt device will be connected. When Displaylink docking station will be plugged in please choose Allow from the notification options.
DisplayLink Manager 1.8.0 App notifies user with a static message window about necessity to allow data flow through USB-C port.
Note: Even if you approve the accessories to connect, this message will remain. In driver 1.8.0 and 1.8.1 there is currently no option to turn it off.
If you don't want to allow known accessories every-time DisplayLink docking station or other USB/Thunderbolt device is plugged, please choose from System Settings -> Security & Privacy -> Security -> Allow accessories to connect -> Ask for New Accessories option.
