Missing driver for SM Bus Controller?

Level 7
In Device Manager it's showing this as not being installed (yellow triangle). I already installed all drivers from official page. Where can I find it?

There's also "PCI Device" and I'm not sure what it is. I disabled USB Audio in BIOS.

ROG Strix Z690-A WiFi D4 board, by the way.

Level 19

Intel Chipset drivers from Windows Update - Optional updates must not be installed if you use .exe installer (either you install your Chipset drivers via .exe or via Windows Update, but do not mix the two). Follow this process to cleanup them :

- Uninstall your current Intel Chipset Drivers package if you have any installed (via Start > Settings > Apps) then restart your PC
- Launch Driver Store Explorer (Right click on "Rapr.exe" > Run as administrator) > Check the boxes of all versions of Intel drivers which .inf contains system word in the System device category (if you find them)
- Check the box "Force Deletion" then click on the "Delete Driver" button then restart your PC
- Install your Intel Chipset Drivers package
