It seems there's no direct method to hide specific tasks from appearing in the Prefect dashboard. Prefect's dashboard is designed to show all task runs for visibility and monitoring purposes. However, you might consider structuring your flow to minimize the visibility of certain tasks by combining them into a single task or using a task worker to handle them in the background.
For more detailed guidance, you can refer to the
Prefect documentation on running tasks in the background or using task workers. This approach might help in reducing the clutter on the dashboard by offloading certain tasks to run separately.
