Not OP. But similar situation. My name is of the form <given nane> <father's given name> (a bit more complicated than that, see my other comment). So if my father's given name is Jack, my name may be Michael Jack. In my native setting I am always referred to as Mr Michael. Very rarely Mr Michael Jack. Never Mr Jack, because that is how my father would be referred to as. So in a western setting I am almost always called Mr Jack and in my mind it is my dad, not me.

As Dr. GivenName in formal settings. As or GivenName et al. in references. As just GivenName in informal settings.
