If all three calamity have it, I can see Yamato having it too. But probably she not have it for two reasons.
She was cuffed witj seastones over so many many years, with means she couldn't train her devilfruit. That is a major point with let me believe that she didn't could awake her df duo the problem with the seastones, as compensation for not able to train her devilfruit she rather train her haki, having even adv Coc like
@Cinera pointed it out.
Second reason, if she really becaming a strawhat,I doubt she already get all massive powerups. With means during travelling with Luffy, she learn awakening and becaming stronger. Storywise and powerlvlwise it make more sense if she awake it later together with sailing with the strawhats rather to have it already.
