Officially, (are there official awards for these) no. He's had two fights against the same guy, GOAT or not. Both fights went the same way, he definitively won the first round and a crazy strange finish in the second. There are fighters with more definitive and meaningful fights this year, MM singlehandedly legitimizing flyweights in the eyes of the fans, Cain proving he is by far and above the best modern heavyweight, Vitor making his case as perhaps the most destructive force in the UFC, Jones officially breaking the LHW title defense record.
There are a lot of cases, and while Chris's feats are incredible in my eyes, he's got to face a steeper challenge in his upcoming defenses next year, and if he pulls through, I highly doubt anyone can top wins over the 3 Brazilians of Doom.
