I know customizations are more limited in reports compared to the dashboards, but is there really not a way to modify the Engagement Summary visualization to get rid of these callout lines and labels? Hoping it’s just something I’m missing.

When you go to edit the widget, at the top of the chart settings, select “display.” From there you can customize showing the label, values, percentages, # of decimal places, pie or donut, and if you want a legend.
