How do you prevent drill-down functionality on a specific visual in Power BI?

To prevent drill-down functionality on a specific visual in Power BI, disabling the drill-down option in the visual settings is the correct approach. When you disable the drill-down option, it effectively turns off the feature that allows users to click on elements of the visual to explore deeper levels of data hierarchy. This action can be crucial in scenarios where you want to maintain a high-level overview without allowing access to more granular details.

By going into the visual's settings and adjusting this option, users will not be able to inadvertently drill down into the data, helping to guide their focus on the intended insights without the distraction or potential confusion that additional layers of data might introduce. This is particularly useful in presentations or reports where clarity and simplicity are paramount.

The other options do not achieve the desired result. Enabling the drill-down option contradicts the goal of disabling it. Removing the visual altogether would eliminate the data representation, which is not desirable if you want to retain it but prevent drill-down. Lastly, changing the data source does not prevent drill-down functionality; rather, it would affect the data being analyzed without addressing the drill-down capability directly.
