On the top right of the dashboards there is a symbol of a clock for the user to setup an auto refresh rate.
Although I can see how useful it can be, I would like to disable for some users to avoid hitting DBs that would not change within a day.
Hi @z3h
You would have to build your own version of Metabase. There’s currently a request for adding a way to customize the options, which would allow you to set very high values (or possible disable it):

You should probably enable caching:
