Spanish is a gendered language and it uses the masculine as general “todos aquí presentes” instead of saying “todos y todas”.

Another example “Somos amigos” “we are friends” Wich I use to refer to male, female and non binary friends.

A good way to address a non binary person in Spanish is by the name and the use of “usted” or “tu” which translates to “you”.

Spanish it’s a complex language and it can include non binary people just as fine.

“without gender specificity”

“Persona no binaria” which uses the femenine, but it can be used with everyone.
