Jetson Nano for My Robot

I currently have the Jetson Nano 2GB in Display Mode. I want to use it in a remote mode where it runs a straightforward python object detection program without the display, keyboard, mouse when powered on. When it detects objects, it sends a signal to an Arduino. How would I configure this so that it runs the program already on the SD Card wirelessly in this manner?

Thank you!
