Cloning a TX2 with the serial debug console disabled

Hi, I have a need to clone a great deal of TX2s and I’ve been following the guide here https://elinux.org/Jetson/TX2_Cloning . Everything works aside from the fact that the serial debug console which I disabled using the guide here http://connecttech.com/resource-center/kdb347-reassigning-disable-serial-debug-connect-tech-tx1-carriers/ is somehow reverted to normal on the new device which unfortunately means that I have to do every device from scratch. Does a way exist to clone a device and keep the serial debug console disabled in the process?

EDIT: flashing the device tree following the cloning process solved the issue.
