You can configure what panel is going to be refreshed from your Async Command. That panel should be a panel with Lazy Load properties (like a Hideable panel). In the Lazy Load properties group there is a progressDelay property. Set that to a large value.
You can find more info about other Lazy Load properties in the online docs in CAF-Designer.
