What chat_mode are you trying?

context

So context works on the knowledge base plus external conversation as well. so maybe you could try a chat engine which does not do external conversation and solely reply based on the context given or if you want to work with this mode only try modifying the system_prompt: https://docs.llamaindex.ai/en/stable/examples/chat_engine/chat_engine_context.html

Okay but for example, I see there's a faithfulness evaluator: https://docs.llamaindex.ai/en/stable/examples/evaluation/faithfulness_eval.html Is there an option to set that up with the context chat engine?
