CIM, the Common Information Model, is a standard information model for representing managed computing resources and their relationships.

The Common Information Model (CIM) provides a way to represent and manage computing resources, including network adapter configurations. In PowerShell 7, CIM commands replace Windows Management Instrumentation (WMI), while working mostly the same way. section 15.2

When no dedicated cmdlet performs an administrative action, query the relevant CIM class, filter the objects, inspect available methods, and invoke the required method. For example, filter Intel network adapter configurations before enabling DHCP. section 15.2

Enable DHCP on selected adapters

Get-CimInstance -ClassName Win32_NetworkAdapterConfiguration -Filter "description like '%intel%'" | Invoke-CimMethod -MethodName EnableDHCP. The returned value indicates the method result and may require lookup.
