Is PCIE x4 bootable for NVMe SSD under Linux

[Atch]

Easy way to boot from nvme is to use armbian nand-sata-install script

Thanks a lot for you reply!

Unfortunately I just gave a try, the script is running well, but when I shutdown the device once it's done and remove the eMMC, while starting, only the green power LED light up, neither the white LED from the board or the green on the NVMe PCIe card light up :-(

If I put back the eMMC, I am starting on it as usual, not on the NVMe.

Here are the steps I have followed:
I have selected the option 6:
   
I have selected a partition on the NVMe:
   
Then the copie was running:
   
And finally:
   

I removed the power cable; the eMMC;
I putted back the power cable and then... nothing excepted the power green LED and the RJ45 port LEDs (I have waited for severals minutes but still...).

I just saw this message during the process:

mount: wrong fs type, bad option, bad superblock on /dev/nvme0n1p3,
       missing codepage or helper program, or other error

       In some cases useful info is found in syslog - try
       dmesg | tail or so.

There it is (after a reboot):

I have no idea what I am doing wrong :-(
