If the PC you are installing on has a DVD drive the best option is to download and extract the drivers and burn them to CD, then in Windows setup when it wants to select a drive/partition click on "Load Driver" and then put the CD in and navigate to it and it should load then NVME driver. If not you can put the extracted drivers on another USB drive (in my experience should be in the PC from bootup) and when you click "Load Driver" select the drive letter for that USB drive.
