The React SDK documents conversation overrides via the overrides option in useConversation. (elevenlabs.io)
The Overrides guide shows how to pass overrides in Python, JavaScript, Swift, and the Web Widget, but does not include React Native. (elevenlabs.io)
The React Native SDK page lists startSession options and callbacks but does not document any overrides parameter. (elevenlabs.io)
If you need per-conversation overrides from a mobile app today, ElevenLabs documents doing so at the protocol level by sending conversation_initiation_client_data with conversation_config_override over the WebSocket API (not via the React Native SDK API). (elevenlabs.io)
Therefore, based on the official docs as of December 2, 2025, the React Native SDK itself does not document support for overrides.
