Tech awards but nothing else. Look the snobby academy don't really like these movies, Even though you are supposed to honor all film right Hollywood?
They don't really even nominate blockbusters like they used too, they nominate films that no one watches & forgets really quickly now.
If the film isn't seen as important to social commentary like Get Out, or Wonder Woman(even though it got no noms) then 9times out of 10 you not getting in. They see these Avengers films as just more Hollywood destruction porn.
Now I do think if there was any mcu film to ever get nominated for something other than tech awards it would be Black Panther. I can see them giving it noms in costume design(didn't SS get a nom & win this? Undeserved if you ask me), cinematography, score, tech, etc.
