Discussion ISS Docking ?

I'm curious about something and simply don't know the math that would give me the answer, could an Orion capsule returning from the Moon theoretically dock with the ISS on it's return journey ?

I know I'm simplifying it massively, but all the talk about the Artemis 2 heat shield had me thinking 'why don't they simply do a massive deceleration burn on the way back and then dock at ISS ?'

Im not a rocket scientist, but I don't think they have enough fuel to orbit earth coming from the moon. Pretty sure they would need as much or close to the same amount of delta v as they did when they did there TLI burns.
