Referencing Event Hub Geo-Recovery DR Alias as a Namespace

Question

We have a DeployIfNotExists policy that creates diagnostic settings on resources in the environments. The policy contains the ARM Template for the diagnostic setting that triggers upon evaluation that the setting does not exist on the resource. Please see below: (This is one example setting for Azure Bastion Hosts)

    "resources": [
            {
              "type": "Microsoft.Network/bastionHosts/providers/diagnosticSettings",
              "apiVersion": "2017-05-01-preview",
              "name": "[concat(parameters('resourceName'), '/Microsoft.Insights/', parameters('profileName'))]",
              "location": "[parameters('location')]",
              "dependsOn": [],
              "properties": {
                "eventHubAuthorizationRuleId": "[parameters('eventHubRuleId')]",
                "eventHubName": "[parameters('eventHubName')]",
                "logs": [
                  {
                    "category": "BastionAuditLogs",
                    "enabled": true
                  }
                ]
              }
            }
          ],

There is a line for Event Hub Authorization Rule ID, which we pass in a parameter. Earlier, we just passed in our primary Event Hub's info. However, some resources that were in a different region would fail because they cannot write cross region to an Event Hub. So with that, now we are using a Geo-Recovery Alias.

We have a Geo-Recovery DR Alias that connects the Primary/Secondary Event Hubs, in two different regions. I would like to pass the EventHubAuthorizationRuleID for this DR Alias, however upon doing that there is the following issue:

    Resource type 'microsoft.eventhub/namespaces/disasterrecoveryconfigs/authorizationrules' is invalid for property 'properties.eventHubAuthorizationRuleId'. Expected types are 'microsoft.servicebus/namespaces/authorizationrules', 'microsoft.eventhub/namespaces/authorizationrules

We get the Authorization Rule for the DR Alias with the following Powershell command:

    PS: Get-AzEventHubAuthorizationRule -AliasName xxxxxxxxxxxxxx -Namespace xxxxxxxxxxxx -ResourceGroupName xxxxxxxxxxxxxxxx


    Id       : /subscriptions/xxxxxxxxxxxxxxxxxxxx/resourceGroups/xxxxxxxxxxxx/providers/Microsoft.EventHub/namespaces/xxxxxxxxxxx/disasterRecoveryConfigs/xxxxxxxxxxxxxxx/AuthorizationRules/RootManageSharedAccessKey
    Type     : Microsoft.EventHub/Namespaces/AuthorizationRules
    Name     : RootManageSharedAccessKey
    Location : 
    Tags     : 
    Rights   : {Listen, Manage, Send}

The above ID is what we pass in as the parameter and is causing the failure. The type in the Powershell response is 'Microsoft.EventHub/Namespaces/AuthorizationRules' even though it clearly contains the 'disasterRecoveryConfigs' portion.

Question: How can we reference the DR Alias so that it reads it as a regular namespace?
