Past shows like Wandavision, Hawkeye, Loki , etc did not have any in park marketing to my knowledge. Most of the MCU films didn’t receive this either.
Most os the time those films get bus wraps and billboards outside the park or in the parking lots as those are fine. Moon Knight being inside the parks via billboards is a green light. I imagine the upcoming Ms Marvel will have the same opportunity albeit harder to market as the word Marvel can’t be used. Or at the very least Kamala Khan may be able to be squeezed in her costume everything but the name.
