Big Sur on MAC Mini M1 uses Bluetooth PAN when the Cinema Display is connected and the Display Ethernet is present.

Does anyone know why Big Sur on MAC Mini M1 uses Bluetooth PAN when the Cinema Display is connected, and the Display Ethernet is present?

Is there a way to have the MAC Mini use the Display Ethernet port and stop using the Bluetooth PAN interface?

With the Ethernet cable connected to the Ethernet port on the Cinema Display, the Bluetooth PAN displays the "Connected" message. When the Ethernet cable is removed from the Cinema Display Ethernet port, the Bluetooth PAN interface displays the "Not Connected" message.
