Clone a Jetson AGX Xavier without using recovery mode

I want to create a clone of my Jetson AGX Xavier on an external drive (SSD or USB flash drive). I do not have access to the recovery, reset or the power button. What would be the best way to achieve this? This backup clone will be used to flash other Jetson devices. Thanks

Sorry but I don’t think this is possible.
Or you boot the device with an SSD or USB stick, and follow the similar method here to create a image of eMMC with dd:
