I don’t know about on a Jetson, but it is possible that if you hit CTRL-c, then it might drop you into an interactive console, either on regular keyboard/monitor or perhaps on serial console.

If you have a problem and really need to save the install, then you could clone the rootfs, repair the clone on your desktop Linux PC, and then flash the repaired clone back in place (warning: requires lots of time and disk space on the PC).
