The Advanced Custom Field (ACF) control allows you to conditionally show or hide blocks based on ACF fields.

How to Use
The Advanced Custom Fields control does have one known issue where blocks do not display as you would expect in the WordPress “preview”. At the top of the editor, there is a preview button that will open the page/post in a new window. It is not (currently) possible to accurately fetch ACF fields on a “preview” page and therefore the ACF visibility conditions may appear to not be working. But don’t worry, they are working and if you view the actual page on the frontend of your site, all block conditions will function as you expect.
How to Disable
If you would like to disable the Advanced Custom Fields control at the block level, simply click on the three-dots icon in the Controls Toolbar and deselect it. That said, if you don’t think you will need this control on your website at all, it can be disabled globally in the Visibility Control Settings.
Note that if this control is disabled globally, any blocks that are actively being hidden by the Advanced Custom Fields control will become visible again.
