Im not sure about that - im no expert at all, but taking a look at the cutaway on this page https://www.dtswiss.com/en/innovations/ratchetexp (the new 240 uses the same technology I think) indicates that you still need to remove the ringnut to get at that bearing. I might be missing something though.
I think the older ones the ratchet was held with just a spring each side, on the new ones one ratchet is screwed in the hub body and you need a tool for that.
