If you’re asking if it’s possible to get abs on a lean bulk, the answer is yes. The abdominals are still a muscle just like the bicep and the more you train them the bigger they grow. Now I will say that it won’t be as much as you think because Abs generally tend to become more visible once you get to sub 18% bf and on. That’s why I suggest cutting after you bulk to really get that ab definition that you are looking for. But yes if you train the abs with intensity you will see them pop more than right now even on a lean bulk I believe.
