我可以想出下面的PS脚本

$Region = "westus" # change region here
$type = "virtualMachines"

$VMSKUs = Get-AzComputeResourceSku | Where-Object { $_.Locations -contains "eastus2euap" -and $_.ResourceType.Contains("virtualMachines") }

$OutTable = @()

foreach ($SkuName in $VMSKUs)
        {       
            foreach($capability in $SkuName.Capabilities)
            {
                if($capability.Name -contains "UltraSSDAvailable")
                {
                    if($capability.Value -eq "true")
                    {
                        foreach($insideCapability in $SkuName.Capabilities)
                        {
                            if($insideCapability.Name -contains "MaxDataDiskCount")
                            {

                                $OutTable += New-Object PSObject -Property @{
                                                                 "Name" = $SkuName.Name
                                                                 "MaxDataDiskCount" = $insideCapability.Value
                                                                 }
                            }
                        }
                    }
                }
            }
         }

$OutTable | select Name, MaxDataDiskCount | Sort-Object -Property Name | Format-Table
