Team Superman (DCEU)vsTeam Hulk (MCU)

Team Superman (DCEU) Cyborg hacks the game.

Team Superman (DCEU) There is no game to hack. They are in a magic arena that has bound them to its rules. Even if he somehow could, the Rift has bound much more powerful characters than him.

With that out of the way... his hacking ability would likely manifest as a debuff or something along those lines and not something he could break the 4th wall with.
