thanks these articles help me a lot to understand CPU PCIe lanes and chipset PCIe lanes. I also asked ASRock technical support and they said that it's fine to fully install the PCIe and M.2 slots, they also said that if you use PCIe to NVMe adapter to make sure "set PCIe/GFX Lanes Configuration to x4x4x4x4 at Advanced\AMD PBS under BIOS then press F10 to save the settings."
