How can I refer to a data disk at first boot on a linux VM?

Question

I've got a requirement to mount a data disk into my filesystem immediately at first boot, with no human intervention. Since device names are unreliable- I figured I would try and create a .vhd file with a labeled empty disk as my data disk's image- so that I can refer to the disk by it's label.

I'm attempting to mount this disk like so-

    "storageProfile": {
      "imageReference": {
        "id": "[resourceId('Microsoft.Compute/images', variables('imageName'))]"
      },
      "osDisk": {
        "name": "[concat(variables('vmName'),'_OSDisk')]",
        "osType": "Linux",
        "createOption": "FromImage",
        "managedDisk": {
          "storageAccountType": "Premium_LRS"
        },
        "diskSizeGB": 32
      },
      "dataDisks" : [
          {
              "lun": 0,
              "name": "[concat(variables('vmName'),'_ContainerDisk')]",
              "createOption": "empty",
              "vhd": { "uri": "https://airgapwmsa.blob.core.windows.net/files/containerdisk.vhd" }
          },
          {
              "lun": 1,
              "name": "[concat(variables('vmName'),'_CephDisk')]",
              "createOption": "empty",
              "diskSizeGB": 1024
          }
      ]
    },

but running into this error-
Deployment failed. Correlation ID: 72545299-4710-46b6-a89b-baada39badc7. {
"error": {
"code": "OperationNotAllowed",
"message": "Addition of a blob based disk to VM with managed disks is not supported.",
"target": "dataDisk"
}
}

Since this approach isn't working- I'd like to either fix this somehow, or find an alternate approach. Any ideas?
