Enable SQL Server protocol using pwsh

Question

I want to enable server protocols using pwsh (not powershell):

I tried this script to enable SQL Server TCP/IP protocol in pwsh:

$cm = Get-CimInstance -Namespace 'root\Microsoft\SqlServer' -ClassName "__NAMESPACE"  | ? name -match 'ComputerManagement' | Select-Object -Expand name
$cnp = Get-CimInstance -Namespace "root\Microsoft\SqlServer\$cm" -ClassName ServerNetworkProtocol
$tcp = $cnp | ? ProtocolDisplayName -eq 'TCP/IP'

$tcp.Enabled = $true

I get this error:

SetValueException: 
Line |
   5 |  $tcp.Enabled = $true
     |  ~~~~~~~~~~~~~~~~~~~~
     | "Enabled" is a ReadOnly property.

How can I do this? I currently use this but it doesn't work in pwsh as assembly System.Management.Automation.PSSnapIn can't be loaded in it.

This might be handy but I didn't find a way to use it.

== EDIT ==

Thanks to @AlwaysLearning, this works in both pwsh and PowerShell (from admin shell):

function Get-SqlServerProtocol($Name) {
    $cm = Get-CimInstance -Namespace 'root\Microsoft\SqlServer' -ClassName "__NAMESPACE"  | ? name -match 'ComputerManagement' | Select-Object -Expand name
    $cnp = Get-CimInstance -Namespace "root\Microsoft\SqlServer\$cm" -ClassName ServerNetworkProtocol
    $cnp | ? ProtocolDisplayName -eq $Name
}

function Toggle-SqlServerProtocol( $ProtocolObject ) {
    Write-Host "Toggle protocol for" $ProtocolObject.ProtocolDisplayName
    $params = @{
        Name = if ($tcp.Enabled) { "SetDisable" } else { "SetEnable" }
    }
    $ProtocolObject | Invoke-CimMethod @params

    Get-Service MSSQLSERVER | Restart-Service
}

$tcp = Get-SqlServerProtocol 'TCP/IP'
Toggle-SqlServerProtocol $tcp

$tcp = Get-SqlServerProtocol 'TCP/IP'
Write-Host "Current TCP/IP status:" $tcp.Enabled
