Yes, you don't require NVMe if you are not planning major upgrade of your system (basically a new computer) in near future. For gaming and web/office tasks good SATA-3 SSD is more than enough. And will be, RTX IO and similar AMD alternative (will appear, I'm 200% sure about that) for DirectStorage are planed to work only over PCIe 4.0 which your MOBO does not have. Obviously you can buy and install M.2 NVMe drive through extension card. However as people said, it is a waste of resources in name of "I have NVMe drive in my PC" (weird finger moves here).
