Orin NX not boot without monitor

I use A603 board and Orin NX 16GB with wifi module

and i followed flash guide for A603 (A603 Carrier Board | Seeed Studio Wiki)

after flashing I setup ssh connection and wifi connection with keyboard and monitor

but at first without monitor, there is no wifi connection confirm on network for finding Orin’s IP.
so after I connect monitor, I can see Orin boot properly and set wifi connection

i think i should connect monitor at first once in a while

is there any tip or optional settings?

You can log in to the A603 remotely using ssh, such as SecureCRT or MobaXterm, instead of the monitor
