You could go without an LES if you can convince NASA that you have sufficient contingencies to not need it (and, of course, you can do almost anything you want on a private flight). SpaceX has been entertaining the idea of not using an escape system on Starship and instead proving its safety through sheer number of flights. Although there also is just a general consensus that the flip maneuver would probably make that necessary even if they had an LES.
