Jetson AGX : looking for a motherboard with display ports on USB-C like the dev kit

The nvidia development kit has a motherboard which have one HDMI video output and two display ports video output merged on the USB-C.
We are looking for a motherboard for Jetson Xavier AGX, which have the same capabilities. And also a nvme slot for a sdd disk, and one UART port / or RS232 port.
Thank you for your help
