Yes. Vacuum pumps help with this with time quite a bit. Also wearing a well fitting bra does wonders, I think it was Valkyrie/Freya who wrote about this quite extensively. I've noted both of these things to make a difference, this is for me very important to deal with as I have super extra wide breast root which goes all the way back behind my armpits. Obviously this trait will last no matter what, but after some years of active vacuum pumping and wearing fitting bras has definitely helped.
Mine are far more centered than before, but obviously there's no way this shape will ever go away as its genetic. Of course surgery could be used to shape them and fat transfers will make even more of a difference.
This is what I mean, my arm is squishing the side in this picture and where the root ends is hard to definite, very typical trait for wide root and shallow projection. Questionably shallow these days as I've grown a lot of projection lately. Well fitting bras are really a lifesaver on this, next one I'll get I will order with shallower but wider cups and wider underwires, perhaps a size or two larger than the cupsize typically has. I'm pretty much forced to wear such bras on which wires sit on top of my sideboob, its not ideas, but otherwise the wires would be really weirdly shaped.
So, get a bra with wide enough wires, then use swoop and scoop method religiously. When its supportive enough, in time it'll start shaping your breasts to become more centered. Also just growing more helps a whole lot.
EDIT:
I forgot to add about bras, get one with wide side panels, the kind which basically makes the band much wider below armpit. Also there are ones which have extra side support panels on the outer side of the cups, these can also be added later on if you're into bra tinkering. I'm supposed to do it for my Ewa bra but laziness might win. I might ask for this when ordering a new one as that'll be completely custom one.
