Yes you can think of it as an inline switch and run only a 3-wire.

Or you can make the outside disconnect the service disconnect and wire the interior panel as a sub-panel. With the first option you would only need 3-wires between the EM disconnect and the service just like in the photo in the OP. Regardle…
