Dynamic default avatar

Hello, I would like to programmatically add default dynamic avatar for users who are not specified theirs avatar.
E.g.
User “Eugene” has no avatar so we show the avatar depending on profile custom fields.
But for user “Andrew” we dont show it, because he has uploaded his avatar himself.
How I can do this?

Also, if there any way to make user avatar by url, and dont upload it to the media library.

Thank you very much!
I really appreciate your help!
