As much as I am an advocate for different options like this in games, I do think especially at this point it's just too much work to not only get it not only programmed as an option and made sure it works with every situation like dialogue, character info retrieving, etc., but also to record different lines as necessary for this (not to mention the possible cultural backlash it'd throw on SE in any area of the world, considering there's still quite a bit of divisive opinions over this). Perhaps I'm not as informed as I should be, but it may just be best to take it as it is or maybe at least have yourself a sort of head-canon for your character so you can still technically have the option even if SE doesn't have it as one.
