We have known that you can since June. "While you can only push one display from your Mac, you can mix-and-match it with visionOS apps. So the practical way to achieve the equivalent of multiple Mac monitors will be to use your virtual Mac display for your power apps – Final Cut Pro, Logic Pro, and so on – while creating separate visionOS panes for things like Safari, Mail, Notes, Maps, and so on. In that way, you’ll get something that is the next best thing to multiple Mac displays, and practically indistinguishable in use."
