There is no factory camber adjustment in the rear. However, there is a small amount of adjustment up front. It's an unconventional adjustment and requires removal of the frunk but it is there. I assure you.
I am referencing this photo from unplugged performance spring install guide. It's a great image to illustrate where the front camber adjustment is.
See the highlighted circles below. These four points is how the "carrier" for the control arm and shock bolt into the chassis. Oddly enough Tesla has allowed the holes to be larger than the bolts' OD's. As a result there is room to shift the assembly in a couple directions. Because it's a circle it will ever so slightly adjust your caster as well. If you're patient enough you can get your #'s to match up pretty well. This is synonymous with a "camber plate" on a more traditional macpherson strut type application. It's really a trippy design. Audi is similar to this but they don't leave slop in the chassis mounting holes.
