USB C DisplayPort not working in Renegade Elite

I’m trying to use the Renegade Elite with a USB-C touchscreen monitor. I can get it to work by using HDMI for the display output and the USB C for touch input, but I can’t get the display to work with only the USB-C cable.

Is DisplayPort (via USB-C_1, since I’m using USB-C_0 for power) supported in the Debian 12 official image? That’s all I’ve tested so far, but if there is better support in another distribution, I’m open to trying others.
