I do my own setups but I tend to leave it to the usual truss rod, bridge, pickup height.
Unless a nut is cut wrong or the slots too large due to a string size change I’ve never had a reason to alter one, if I do it’s usually a trip to the tech for a new one.
I’m more than capable of doing the job but by the time I’ve got the new nut and set up to do it it’s just as easy to leave it to the pros who have the gear to hand.
