Get-AzVMSize -Location "West US"

The command above returns a list of all Azure VM SKU sizes in this format.

Is there an Azure PowerShell command, C# SDK API or REST API call that can give me a list of all available SKUs that are enabled for confidential computing? There is some document list, but I would like a way to pull this programmatically. I do not see a documented way so far to this in PowerShell either, any suggestions?

The Azure management API has an endpoint that allows you to list resource skus.

https://management.azure/subscriptions/{subscription-id}/providers/Microsoft.Compute/skus?api-version=2021-07-01&$filter=location eq 'westus'

The response contains skus for all types of compute resources, including virtual machines (filtering by region is recommended as the response will otherwise be close to 60MB).

The capabilities array contains detailed information on what the sku can be used for. You can filter the response using Powershell.

$apiResponse = Invoke-WebRequest -Method Get `
    -Uri "https://management.azure/subscriptions/{subscription-id}/providers/Microsoft.Compute/skus?api-version=2021-07-01&`$filter=location eq 'westus'" `
    -Headers @{
        "Authorization" = "Bearer $($accessToken)"
        "Content-Type" = "application/json"
    }

($apiResponse.Content | ConvertFrom-Json -Depth 99).value | Where-Object {
    $_.ResourceType -eq "VirtualMachines" -and
    $_.Capabilities.Name -contains "ConfidentialComputingType"
} | Select-Object Name, Tier, Family, Size, @{ 
    Name = "ConfidentialComputingType"; 
    Expression = { ($_.capabilities | Where-Object {$_.Name -contains "ConfidentialComputingType"}).value -join "," } 
} | Format-Table

This will output a table containing the VM sizes and the confidential compute type.

Name                 Tier     Family                 Size        ConfidentialComputingType
