Is there a way to quiet the progress bar printout?

Something like a `verbose` flag to turn on or off the progress bar prints
Progress bards are great for local development but not much needed while deploying it as a service. having the option to toggle it on and off is desirable.

I'd be happy to take a look and submit a PR if needed

No file or test is named. Search the codebase for progress-bar printouts and trace them to the public entry point; confirm how service users could toggle them without affecting local defaults. Done means the option suppresses progress output when disabled and preserves it when enabled, with coverage for both modes.
