Architect Data Action timeout hardcoded at 3s but API takes 5s

The REST call inside my data action is timing out because the default 3-second limit is too short for this endpoint. I can’t find a setting in the UI to bump it up. Is there a way to override this via the JSON payload or an API call to /api/v2/architect/dataactions? The call fails with a generic timeout error after exactly 3000ms. I need it to wait at least 5 seconds. Here’s the current config.

{
 "id": "123",
 "name": "FetchUser",
 "timeout": 3
}
