Import powershell module in guest configuration script resource

Question

Hi,

I'm trying to create a guest configuration to monitor if the VM enabled Windows defender realtimeMonitoring.

Here is my code:

    Configuration EnableRealtimeMonitoring  
    {  
        Import-DscResource -ModuleName 'PSDscResources'  
      
        Node localhost  
        {  
            Script EnableRealtimeMonitoring  
            {  
                GetScript = {  
                    $RealtimeMonitoringEnabled = Get-MpComputerStatus | select -expandproperty RealTimeProtectionEnabled  
                    return @{ 'Result' = "$RealtimeMonitoringEnabled" }  
                }  
                TestScript = {  
                    $state = [scriptblock]::Create($GetScript).Invoke()  
      
                    if( $state.Result -eq 1 )  
                    {  
                        Write-Verbose -Message ('Current state of RealtimeMonitoringEnabled is {0}' -f $state.Result)  
                        return $true  
                    }  
                    Write-Verbose -Message ('Current state of RealtimeMonitoringEnabled is {0}' -f $state.Result)  
                    return $false  
                }  
                SetScript = {  
                    Set-MpPreference -DisableRealtimeMonitoring $false  
                }  
            }  
        }  
    }  

However, while testing, the PowerShell returns following error:

Error Message: PowerShell DSC resource                         | MSFT_ScriptResource  failed to execute Test-TargetResource functionality with error message:                          | System.InvalidOperationException: The test script threw an error.  --->                                               | System.Management.Automation.MethodInvocationException: Exception calling "Invoke" with "0"                           | argument(s): "The term 'Get-MpComputerStatus' is not recognized as a name of a cmdlet, function,                      | script file, or executable program. Check the spelling of the name, or if a path was included, verify                 | that the path is correct and try again."  ---> System.Management.Automation.CommandNotFoundException:                 | The term 'Get-MpComputerStatus' is not recognized as a name of a cmdlet, function, script file, or                    | executable program.

     | correct and try again.    at  
     | System.Management.Automation.ExceptionHandlingOps.CheckActionPreference(FunctionContext funcContext,  
     | Exception exception)    at System  

The command Get-MpComputerStatus is a common term in the PowerShell module Defender, but I don't know how I can import this module in the guest configuration script. I tried lots of methods including:

Import-Module Defender  
Import-DscResource -ModuleName 'Defender'  
Import-DscResource -Name 'Defender'  

but either one worked.

Could you please tell me how can I import PowerShell modules in the guest configuration script?

Thanks!
