Could flash os imge to nvme ssd for xavier?

I bought a nvme2.0 ssd for my xavier. Could someone know how to install os image in nvme2.0 ssd and not the emmc! thank you very much!

The official flash.sh tool is not able to flash anything to external drive. You have to copy the file system to the nvme drive manually.
