Data Studio allows users to change the "Data freshness" from the settings of the data source:

However this settings does nothing with Supermetrics Data Studio connectors, and only works with Google’s own connectors.
Supermetrics Data Studio connectors requests data when the user does something that triggers it. Such events are for example:
- Refreshing the report
- Loading the report page
- Adding/updating elements of the report
So in conclusion: Supermetrics users can ignore this setting completely.
