• The following Azure document says

  • Enable managed boot diagnostics using Azure Resource Manager (ARM) templates

 "diagnosticsProfile": {
     "bootDiagnostics": {
         "enabled": true
      }
 }

Ref: https://docs.microsoft.com/en-us/azure/virtual-machines/boot-diagnostics#enable-managed-boot-diagnostics-using-azure-resource-manager-arm-templates

• The following Terraform document also mentions

  • A boot_diagnostics block supports the following:

    ・enabled - (Required) ty

    ・storage_uri - (Required) The Storage Account's Blob Endpoint which should hold the virtual machine's diagnostic files.

I belive the enabled flag has been removed from the linux and windows virtual machine resource.
To enable boot diagnostics you set the boot_diagnostics block and give in the storage_account_uri. If you pass in a null value a Managed Storage Account will be used to store boot diagnostics.
