hello Robin.sun,

please access Jetson Xavier NX Product Design Guide and check the chapter-12.3 for the UART chapter.
the Jetson Xavier NX brings three UARTs out to the main connector, you should also refer to [Figure 12-5. Jetson Xavier NX UART Connections].
you should also refer to Topic 154398 for the steps to disable debug console.
