It's already holds agetty(Serial Console).

Plsease teach me about stop agetty and use Nextion display setting.
It's port supplies GND and +5V,It's conenects,Can Display Intial Screen,but no change Infomation.
The Nextion Display was checked at USB to Serial dongle(/dev/ttyUSB0).

Thank you.

I don't believe that its going to work, the serial console is used as *THE* output device on those (since there is no video) before the kernel is even booted.

If I remember right they have two UART available on the GPIO pins already, you would do better using one of those.
