In the case of Noctis yes, i might be wrong. He has strong jaw x)
But what i wanted to say is : when i talk about someone androgynous i look at the shape of the face, without counting the hair, eyelashes or anything that can be changed.
A better example is Cloud :

And look at lightning :

Guive to Cloud the same hair as Lightning, some makeup and he'll look very feminine. Yet with his current hair and absence of makeup he looks masculine.
Viera have the same type of face but have thick eyelashes by default that guive them a more feminine look without any chance of adjustment. With many of the haircuts being cute, achieving something similar as Cloud is more difficult. It's close sure, but when i tried with my character there are moments where he just looks really close to a girl :
I'm not saying viera shouldn't be girly, it's just a nice idea for ppl who want something closer to Squall or Cloud. I don't think it's something that breaks the lore or anything.
Even for the beard a more masculine face is needed, if it's too mutch on the girl side it will look weird. Unless you really want to have a girl with a beard, then it's ideal.
