Turn Knowledge Base On or Off for AI Chat

It would be really useful to have a simple toggle to turn the knowledge base on or off for an AI chat experience. Sometimes you want the assistant to act as a pure conversational AI without pulling from any RAG sources, and other times you want it grounded in your knowledge base for more accurate, support-focused answers. Having a clear setting to switch between those modes would make the feature much more flexible for different use cases. This would be especially helpful for teams that want to use the same chat interface for both general AI interactions and knowledge-backed customer support.
