Note: For this question, when I refer to \"Windows drivers\" I mean .inf and associated files which can otherwise be installed by right-clicking the .inf and clicking \"Inst
Not only are there not PowerShell cmdlets for this, it seems there isn't even managed code to do it within the .Net framework (what follows is basically a translation of that answer into PowerShell).
Luckily, the .Net framework can call windows APIs through platform invoke (p/invoke), and PowerShell can do so too.
The linked answer shows how to do it in C#. To do it powershell we'll use the same signature that was generated in that answer, and use it with the Add-Type cmdlet (see example 5) to make it available to your script.
$signature = @"
[DllImport("Setupapi.dll", EntryPoint="InstallHinfSection", CallingConvention=CallingConvention.StdCall)]
public static extern void InstallHinfSection(
[In] IntPtr hwnd,
[In] IntPtr ModuleHandle,
[In, MarshalAs(UnmanagedType.LPWStr)] string CmdLineBuffer,
int nCmdShow);
"@
$Win32Functions = Add-Type -MemberDefinition $signature -UsingNamespace System.Runtime.InteropServices -Name Win32SInstallHinfSection -Namespace Win32Functions -PassThru
$Win32Functions::InstallHinfSection([IntPtr]::Zero, [IntPtr]::Zero, " ", 0)
See the MSDN documentation for InstallHinfSection for details on the parameters (particularly the string format).
