In order to prepare the Rock 5B to be able to boot from the NVMe SSD several steps need to be performed.
These steps are to be performed when the Rock 5B is booted into Linux (i.e. from eMMC or microSD card) with network connectivity.
If you don't have network connectivity then just copy the image files to other external media (i.e. USB stick) to be able to access them.
