Direct Query: Do not render visual until approved

Yes, you can change the default behavior of Power BI Desktop/Service to prevent it from instantly rendering visualizations after changing them.

To do this, you can go to the "File" menu in Power BI Desktop, click on "Options and settings", and then choose "Options". In the "Current File" section, you should see an option called "Auto date/time/timezone". If this option is checked, it can cause Power BI to automatically update visualizations as soon as changes are made. To disable this behavior, uncheck the "Auto date/time/timezone" option.

Once you have disabled this option, you can make changes to your visualizations (e.g., add columns) without Power BI automatically rendering the results. When you're ready to update the visualizations with the new changes, you can hit the "Apply" button that you mentioned. This will refresh the visualizations with the latest data from your Direct Query source.
