I don’t get the point here.
The board has two USB ports. One is connected to the builtin USB of the ESP32-S3 and the other is connected to a USB-to-UART chip which is then connected to the UART of the ESP32-S3.
If you are using the Arduino Framework, you can specify how the Serial object should behave and which ports should be used for output.
