I know at least two people who are autistic but sufficiently verbal and highly-educated to be accepted as being within the norms of their milieu. Both of them were taught formal manners (the local equivalent of "Miss Manners' Guide To Excruciatingly Correct Behaviour") and interact socially and professionally on that basis. As far as I can see, this works for them, being in a hierarchical Asian society that values educational attainment, especially in STEM subjects, since formal manners are automatically associated with high social class as well.
