Yep two ways to do that. First and simplest is pass max_steps: 1, eg:
Omni.stream_text(model, context, max_steps: 1)
Also tools themselves can be schema-only - they don’t need a function handler attached. So if any of your tools don’t have a function handler then it will just stop there with a stop_reason: :tool_use and then it’s up to you to handle the rest and feed the results back.
