It’s quite possible! It’s gotta depend on how Thor: Ragnarok and Black Panther end, because if that’s the case, one of them has to convey to the audience that the Avengers know Thanos is coming for real.
It’s definitely the case that he’s in disguise. My guess is he’s secretly meeting with Wanda, who is still on the run because of the Accords.
Of extra interesting note, Wanda is wearing clearly different clothes, implying these scenes take place over more than one day (like maybe he spent the night…).
