ANSWER:

No, this is not permissible. 

You can go and have dinner with them some other time. 

Sheikh, if A convert has non Muslim family, is it haram to have dinner at their house (no ikhtilaat, it’s just their parents and siblings) on Christmas Eve without buying presents, signing or wishing happy Christmas? Can a person use the dinner as a method of being together with the family as some cultures only get together for celebrations?

Greeting” means to congratulate on the birth of prophet Isa A.S. As Christmas means birth of Prophet Isa A.S (Reference: google) (Also my Christian friends agree to this fact). Muslims do congratulate their Muslim fellows on the birth of Prophet Muhammad PBUH. Then why is it not permissible for a Muslim to say “Merry Christmas”? I can’t understand this hypocritical behaviour.
