 |  | `DOCLING_SERVE_SHOW_VERSION_INFO` | `true` | If enabled, the `/version` endpoint will provide the Docling package versions, otherwise it will return a forbidden 403 error. |
 |  | `DOCLING_SERVE_ENABLE_REMOTE_SERVICES` | `false` | Allow pipeline components making remote connections. For example, this is needed when using a vision-language model via APIs. |
 |  | `DOCLING_SERVE_ALLOW_EXTERNAL_PLUGINS` | `false` | Allow the selection of third-party plugins. |
+|  | `DOCLING_SERVE_ALLOW_CUSTOM_VLM_CONFIG` | `false` | Allow users to specify a fully custom VLM pipeline configuration (`vlm_pipeline_custom_config`). When `false`, only presets are accepted. |
+|  | `DOCLING_SERVE_ALLOW_CUSTOM_PICTURE_DESCRIPTION_CONFIG` | `false` | Allow users to specify a fully custom picture description configuration. When `false`, only presets are accepted. |
+|  | `DOCLING_SERVE_ALLOW_CUSTOM_CODE_FORMULA_CONFIG` | `false` | Allow users to specify a fully custom code/formula configuration. When `false`, only presets are accepted. |
 |  | `DOCLING_SERVE_SINGLE_USE_RESULTS` | `true` | If true, results can be accessed only once. If false, the results accumulate in the scratch directory. |
 |  | `DOCLING_SERVE_RESULT_REMOVAL_DELAY` | `300` | When `DOCLING_SERVE_SINGLE_USE_RESULTS` is active, this is the delay before results are removed from the task registry. |
