b450 pro4 m.2 nvme is not detecting

Usage of M.2 slots is very dependent on external factors. If you have other pcie devices plugged into certain PCIe slots, those might disable M.2 slots. On some motherboards plugging in something into certain SATA slots might disable M.2 slot.

System set up description is essential here. Please provide detailed system specs and what PCI-e/SATA ports are being used for us to help you out.

checked the driver in an asus mobo and it works.
i guess asrock mobo is either faulty or this is a QVL problem, but honestly WHO CHECKS QVL for nvme drives really...
