I have never owned macaws.
But I have owned amazon parrots (multiple) for years.
Generally speaking more parrots = more noise.
You have to take individual behavior and circumstances into consideration.
I have a rescue amazon (Luna) that was a real screamer. She spent at least some time in a wild flock before being found too weak to fly.
I got her a partner of the same species and was very lucky that they got along.
Does Luna still scream, yes and so does her partner.
But it’s not all the time just morning and evening like you expect
While I did get the Merlin as a partner for Luna I bought him for myself as well.
