first get the location nvme drive is located at:
lsblk
mine was always mounted at nvme1n1. Then check if it is an empty volume and doens't has any file system, (it mostly doesn't, unless you are remounting). the output should be /dev/nvme1n1: data for empty drives:
sudo file -s /dev/nvme1n1
Then do this to format(if from last step you learned that your drive had file system and isn't an empty drive. skip this and go to next step):
sudo mkfs -t xfs /dev/nvme1n1
Then create a folder in current directory and mount the nvme drive:
sudo mkdir /data
sudo mount /dev/nvme1n1 /data
you can now even check it's existence by running:
df -h
