I think what's only available in Enterprise/Education editions is the users ability to configure that filter themselves, while what Brave is doing should be available everywhere, where the application itself registers as a browser + what specific window is "sensitive" (which Brave registers all windows as, when the toggle is active). That's my understanding at least.
The linked document is about how IT admins can manage the filter via policy, which is exclusive to Enterprise/Education. Users can set up filters through the settings UI (on all editions).
