Show Camera feed on TVico as Standalone device

I’m currently trying to get the camera image/feed from a TVico device [Orbbec Persee] to be shown in a TV.
I’m not using as a WebCam or connected to a Windows or Mac or Linux.

I’m just using the TVico connected to a TV through the HDMI cable.
Can I show the Camera feed/image this way?
Also I’m using Unity for prototyping.

I tried use Unity’s “WebCamDevice” or “WebCamTexture” and nothing is shown.

I was able to get the Color camera render into a RawImage on a Unity application.
But now I need to change the output from the HDMI from landscape to portrait because I want to use my TV as a mirror.

Anyone can help changing the device orientation?
