+### 5. **Aggregated Deployment with Config** (`agg-with-config.yaml`)
+Aggregated deployment with custom configuration.

+**Architecture:**
+- `nvidia-config`: ConfigMap containing a custom trtllm configuration
+- `Frontend`: OpenAI-compatible API server (with kv router mode disabled)
+- `TRTLLMWorker`: Single worker handling both prefill and decode with custom configuration mounted from the configmap
