That's the thing, he might just have that. The no shirt scene in MOS was done at Snyder's bidding because Cavill was wearing the body fit suit and looking very big and muscular, and Snyder said he didn't want the audience to think it was a rubber suit, so he put in a shirtless scene to show that Superman/Cavill was actually powerfully built.
If Snyder wants to show the extent of Batman's physical prowess, he might put in a no shirt scene.
