title: How to edit a Grafana dashboard which keeps freezing due to a bad query
body: <p>I have a Grafana dashboard to which I have unfortunately added a graph which freezes the browser tab due to the large number of time series it tries to load. I am unable to edit it as the dashboard freezes within seconds of loading, rendering the entire dashboard unusable.</p>
  
  <p>Is there a way to open a Grafana dashboard in some sort of "safe mode" where it will not attempt to pull data or render the panels, so that bad queries like these can be fixed?</p>
