Here a more complete example that can manage multiple NVMe disks:

mkdir -p /scratch/fusion
NVME_DISKS=($(nvme list | grep 'Amazon EC2 NVMe Instance Storage' | awk '{ print $1 }'))
NUM_DISKS=${#NVME_DISKS[@]}
if (( NUM_DISKS > 0 )); then
  if (( NUM_DISKS == 1 )); then
    mkfs -t xfs ${NVME_DISKS[0]}
    mount ${NVME_DISKS[0]} /scratch/fusion
  else
    pvcreate ${NVME_DISKS[@]}
    vgcreate scratch_fusion ${NVME_DISKS[@]}
    lvcreate -l 100%FREE -n volume scratch_fusion
    mkfs -t xfs /dev/mapper/scratch_fusion-volume
    mount /dev/mapper/scratch_fusion-volume /scratch/fusion
  fi
fi
chmod a+w /scratch/fusion

You need to install yum install nvme-cli
