Description of Feature or Work Requested

Currently, the CLI for Application Gateway does not support the newly introduced properties to disable default server header from application gateways. These properties have already been added to Swagger and PowerShell and published. We want to have similar support in Cli too to sync all clients and finish the entire release process across all clients

Hi abhi20091999, thanks for the feature request. The Application Gateway resource type, disableDefaultServerHeader property, affected update/show/list commands, and minimum API version 2025-09-01 are already clear.

Before scoping implementation, please share the remaining acceptance details:

• The Azure CLI version/build you are targeting and one concrete proposed az network application-gateway update invocation, including the new option and value.
• A minimal sanitized request/response example showing the property's exact JSON nesting and expected show/list output. Please specify the intended behavior when the option is omitted, set to true, and set to false.

A small example is enough:

Azure CLI version:
Proposed update command:
Request property JSON:
Expected show/list JSON:
Omitted / true / false behavior:

No need to resend the resource type, API version, or links already supplied. Please omit credentials and customer-identifying values. I'll pick this up automatically once you reply.
