Caster/Camber is set by a bushing on top of the steering knuckle. The upper ball joint goes up thru it and the nut for the ball joint is drawn down onto the bushing. The bushing has a lip that has an angle to set caster/camber. There is a flat side on the bushing that locks against a vertical lip of the steering knuckle to keep the bushing from spinning in the knuckle
The factory bushing is fixed for caster/camber and while you can buy replacement fixed bushing the most common is an adjustable bushing. Here is an example from Moog.
