How to delete Global Parameters using Powershell command - azure-data-factory

Question

I have created a number of Global Parameters in DEV Azure Data Factory which is being used in many pipelines. I have deployed those Global parameters using ARM template to our QA environment.
Now I have deleted few parameters from Dev environment and when I re deployed the ARM template, those parameters are not getting deleted from QA environment.
I did not find any other way to delete from QA environment as we do not have delete permissions in QA.
Can you please suggest what are the next steps? I am looking for a powershell command way to delete those parameters.

param
(
[parameter(Mandatory = $true)] [String] $globalParametersFilePath,
[parameter(Mandatory = $true)] [String] $resourceGroupName,
[parameter(Mandatory = $true)] [String] $dataFactoryName
)
Import-Module Az.DataFactory
$newGlobalParameters = New-Object 'system.collections.generic.dictionary[string,Microsoft.Azure.Management.DataFactory.Models.GlobalParameterSpecification]'
Write-Host "Getting global parameters JSON from: " $globalParametersFilePath
$globalParametersJson = Get-Content $globalParametersFilePath
Write-Host "Parsing JSON..."
$globalParametersObject = [Newtonsoft.Json.Linq.JObject]::Parse($globalParametersJson)
# $gp in $factoryFileObject.properties.globalParameters.GetEnumerator())
# may be used in case you use non-standard location for global parameters. It is not recommended.
foreach ($gp in $globalParametersObject.GetEnumerator()) {
Write-Host "Removing global parameter:" $gp.Key
$globalParameterValue = $gp.Value.ToObject([Microsoft.Azure.Management.DataFactory.Models.GlobalParameterSpecification])
$newGlobalParameters.Remove($gp.Key)
}
$dataFactory = Get-AzDataFactoryV2 -ResourceGroupName $resourceGroupName -Name $dataFactoryName
$dataFactory.GlobalParameters = $newGlobalParameters
Write-Host "Updating" $newGlobalParameters.Count "global parameters."
