Dell Latitude 7030 rugged Extreme- tablets pogo pin connector pin layout?

I am currently working with a Dell Latitude 7030 Rugged Extreme Tablet and would like to inquire about the pinout and protocol specifications of the pogo pin connector located on the back of the device.

Specifically, I am interested in understanding whether this connector uses standard interfaces such as USB (e.g., USB 2.0/3.0), serial (UART), or if it is based on a proprietary communication protocol. My goal is to evaluate the feasibility of developing a custom adapter or docking solution that interfaces with the tablet via this connector.
