there are a few ways to get an NVMe drive in your system. M.2 PCIe based drive. you can also buy a PCIe card to mount one as well as a PCIe card that is integrated. There is also a U.2 which was aimed more towards Server architecture.

a x1 slot has a single direction BW of 2.5 Gbps/200MBps and x4 slot can move 1 Gbps/800MBps

so most NVMe based m.2 drives are wired to 2 or 4 lanes. In your case a 4x PCIe slot would be a great deal of performance even over the normal SATA bandwidth.

the PCIe cards do have a fair amount of cost added to them.

This is the first I've heard of NVMe. I just read
https://en.wikipedia.org/wiki/NVM_Express , and now have some questions:

1) Can I replace the spinning platter 2.5" hard disk in my 5 year old
laptop with an NVMe device? My research tells me an NVMe must plug
into a PCIe slot rather than a SATA slot.

2) Do you fstrim NVMe-hosted partitions the same way you do for SSD?

3) When you install an NVMe card in a PCIe slot, what device name shows
up? Is it sd-whatever, or something else?

4) If my desktop has a free PCIe slot, does that mean I can plug in an
NVIe drive and use it?

Thanks,
