However the advantage of booting from SSD instead of eMMC is rather limited -- you will only see one or two seconds faster on boot. It is usually acceptable to let the device boot from eMMC while using NVME SSD as extra storage.

If you do want the device to boot from NVME SSD, you can migrate the root file system to SSD. Below are the instructions.
