Hi,
There is no automatic way to convert the query to PowerShell command but what stops you from executing the query via PowerShell? Other option if you want to get the data from Azure Disk is to run Get-AzDisk. Running arg queries is faster in scale as you can run it against multiple subscriptions and ARG executes faster. Get-AzDisk have to be ran by subscription and uses the Rest API which is slower than ARG.
