    string cpuInfo = "";
    ManagementClass managClass = new ManagementClass("win32_processor");
    ManagementObjectCollection managCollec = managClass.GetInstances();

    foreach (ManagementObject managObj in managCollec)
    {
        if (cpuInfo == "")
        {
            //Get only the first CPU's ID
            cpuInfo = managObj.Properties["processorID"].Value.ToString();

I can't tell you how to change CPU Id's because I don't think that's possible but I can tell you how to write concise code,

private string getFirstCPUID() =>
    new ManagementClass("win32_processor")
      .GetInstances()
      .FirstOrDefault()?
      .Properties["processorID"]?
      .Value?.ToString();

Per MSDN:

https://docs.microsoft.com/en-us/windows/desktop/cimwin32prov/win32-processor

ProcessorId

Data type: string

Access type: Read-only

This value comes from the Processor ID member of the Processor Information structure in the SMBIOS information.

There's no way to do this from c# code. The use cases I know for this involve using some sort of VM or Hypervisor solution that lets you emulate different harware. This is sometimes helpful for things like a VPN client that enforces being on physical hardware and not a VM.
