If you want less understeer you need more front camber*. Quite similar to FWD that's harder to accomplish with xDrive. You can't fit M3 control arms like you'd do on a RWD E90/E92. Had an E92 xDrive from new once and left it stock. My next BMW has been RWD and if I'd get another one it'll be RWD too that's for sure.
*stock camber is just half a degree
