I found this diver AMD PCI Bus Driver Version 20.10.0.0000 to the following link https://necacom.net/index.php/amd/catalyst-driver/12453-amd-pci-bus-driver-version-20-10-0-0000
Windows automatic driver in Device Manager is System devices -> PCI Express Root Complex
This driver is not included to regular chipset drivers.
Should I install it via Device Manager or not?
The PCI Bus driver belongs to Radeon, not Ryzen. Also, do not use Windows Device Manager because your computer may not start after the driver installation. So you may have to install Windows again.
According to Microsoft, this is a scam. Is AMD Catalyst Control Center needed for Windows 10? - Microsoft Community
