HDMI_CEC pin usage questions when the interface is configured in DisplayPort

By comparing the Figure 9-1 “DP and eDP connection Example” and Figure 9-3 “HDMI Connection Example” on D.G V1.2, it is clear the CEC pin is not connected when the port is used as DP2.

Question is, why the P37337 development board has the pin connected to a DisplayPort connector? Any reason behind?
We simply wish to confirm if the CEC pin needs to be connected between ORIN module and a mini-DP connector in our design.

That’s for DP++. It is not used if DP only.
