Programmatic refresh of dashboards for near real-time data rendering

Hello.
I have activated capacity pricing in order to get my dashboards update every minute (I use direct SQL query from Redshift for dataset).
But when I try to publish my dashboard there is no “Enable auto-refresh for visualizations” button.
My boss has reached to Quicksight account manager, as it’s suggested here and it’s been over 2 weeks without a clear answer.
Is there any API method to programmatically refresh my dashboard every minute?
I couldn’t find it in documentation.

Thank you!
