I've asked this question a few times, and the answer is always no, there is no baseline preload adjustment.
Ride height adjustment would be the best, and a higher spring rate option would be great as well, but neither is available. I have heard of a calibration procedure for ESA, performed by the GT-1 at the dealer, but am not sure what it achieves.
A little prodding of a dealer might reveal that the calibration procedure might end up with a better baseline preload.
