Windows 10: Error 32 in Device Manager after disabling Intelppm (C states?)

I'm having some trouble disabling C-States. I have an Aurora R7 i7-8700 with a highly locked BIOS (v. 1.0.22); Intel SpeedStep and SpeedShift can be disabled but there is no option for C-States. For those without the C-States option in BIOS several posts suggested to disable (value: 4) the registry key "Intelppm" from its manual state of 3, but after restart all cores under "Processors" in Device Manager show an Error 32 with the following message: "A driver (service) for this device has been disabled. An alternate driver may be providing this functionality. (Code 32)". I have many drivers disabled in registry but this is the only one to cause such an error. Currently Intelppm is set to 3 again and the Error 32 is gone. Would it be okay to ignore this error and disable Intelppm or must Intelppm be enabled?

Giga EX58 Extreme, C states will not disable

Open Control Panel > Power Options > Select the "High Performance" plan. It will override any hardware-level C-state management, and tell the processor to stay in its maximum performance C-state.

Basically, Code 32 indicated the start type for this driver is set to disabled in the registry. You can refer the

However, you can go ahead and try these steps and let us know the status.

Uninstall the HID Driver.

1. Press Windows + X key from the keyboard and select
   Device Manager.
   
2. Expand HID device. Right click on the device listed with warning sign and select
   Uninstall device.
   
3. You will receive a prompt, make sure you check the box for
   Delete the driver software. Then click OK.
   
4. Please uninstall the device with the warning sign (PCI Device).
   
5. Restart the PC and connect your IPhone and check the driver status.

Please reply us with the resolution, so that we can approach the issue with more clarity.
