Why do you say that? I would assume the auto levelling has any preload setting up to and including MAX at its disposal, so not sure what you would gain by selecting MAX, and you might find that it gives more preload than needed. The only beef I have with AUTO is that it does not make the preload adjustment until after you ride off. If you were previously riding solo and then on your next outing you have a pillion on board, the rear of the bike sags badly and is underdamped for the new load, and you have to ride off in that state until the system adjusts, which is not comfortable and arguably not safe. Also, as I found, if you don't retract the sidestand before the pillion gets on it can then be impossible to do so.
I thought a workaround for this might be to start off in MAX and change to AUTO later, but you can only do this if stopped, and then it just appears to drop the bike down to some default setting and only adjusts properly for the actual load once you start riding again.
