Any wishbone or macpherson strut suspension will change camber at different ride heights. The lower arm needs to push the bottom of the wheel out slightly during suspension compression, as it can’t keep a constant track as it rotates and you don’t want it switching from negative to positive camber or having a high roll centre (which will be the case if the lower arm is too high at the outside pivot compared with the inside pivot).
Many SUVs will have positive camber (with low cornering grip) at higher ride heights. For fixed camber you need solid axles (normally zero camber) or semi-independent de-Dion rear suspension. Trailing arm suspensions will have less camber change, but are compromised in other ways.
Active suspensions with zero or artificial opposite roll can have little camber change, but the feel of the car seems to be weird and non-intuitive, so I don’t know of any sporting car that will counteract natural roll completely.
