   - `Arm`: Inputs are Azure ARM template parameter files with a `.json` extension.
   - `Yaml`: Inputs are YAML files with a `.yml` or `.yaml` extension.
 - **AdditionalProperties** *(optional)*: A collection of custom top-level properties to inject into the final output. Use the `ItemGroup` syntax to pass key-value pairs.
+- **IsQuietMode** *(optional, default=false)*: Only emits warning and error level logs if true.
