Can you call an Imam BABA?

Salam, This might be a really childish question but please let me know….

I have listened to scholars mentioning about Imam e zamana that he loves his shia and sees our state and has a fatherly affection for us…..

So i was wondering if you were (a non syed) someone who does have a father so not an orphan can call out to him in this manner

Please guide me and correct me i do not want to disrespect or cross my boundaries 🙏
