Do I need to remove this DT Swiss ring nut? (360 hub)

I’m swapping bearings on Roval Traverse rear hub, which is said to have DT Swiss 360 internals, 3-pawl.

Do I therefore need to remove the ring nut as per normal DT Swiss instructions? If so I’ll need to source the tool.

There is such a small difference between the diameters of the ring and the bearing, are all DT Swiss hubs like this/is it normal??
