You need a special console cable to access CLI
Settings: RJ45 Console Port
RJ45 serial console port for Command Line Interface (CLI) management Use an RA5-toDB9, serial console cable, also known as a rollover cable, to connect the Console port to your computer. Then configure the following settings as needed:
•Baud rate 115200
•Data bits 8
•Parity NONE
•Stop bits 1
•Flow control NONE

USB-C connection could be used for the same purpose

Unfortunately not:
The RJ45 console port is a serial port to access the CLI (you also need a special RJ45-2-DB9 cable). In other words, to somehow access the shell in the event of a problem. As far as I know, it cannot be converted to a normal network port.
The USB port has the same purpose. This also only gives you access to the Unifi CLI
