I would just set it to 10mm. It's not going to "break" anything. It appears that what happens is the DME will try to adapt closer to the 10mm target as it can get, where if you leave it at the stock setting it will be closer to 9.5-9.6mm in reality.
It also means that any valve lift mods that work on the N52 should also work on the N55.

I agree any mod for the N52 will work for the N55, but I am not following your logic on the only 9.5-9.6mm stock lift. The stock table lists 9.8mm at 100% throttle, why would you think it is only reaching 9.5-9.6mm? Throttle is at 100% in logs, so it's not trying to limit boost or close the valves.
I just want to compare what the stock N52 table lists vs what the literature has as max lift.
