Un-sync only floating viewport?

Any chance I can keep my floating viewport on a second monitor independent from other viewports?

Very specific detail: The above still stands, in general, but wanted to specify that when I use my SpaceMouse Enterprise button “FIT,” it ZoomsToSelected on all views, even when they are not “sync’d” in Options, which is fantastic. Best of both worlds. But I often use the floating viewport on my 2nd monitor to maneuver around a Reference Model I’ve been given, and I’d love the ability to keep this viewport independent of the other viewports without locking it.

Obviously, I could have a separate instance of Rhino open with the Ref Model, etc, but figured I’d ask…
