Is it obligatory to change the name "Mary" for a newborn girl, despite the father's intention that it is another pronunciation of the name "Maryam," and this after learning that it might be a Christian name?

The name "Mary" must be changed because, although it is another pronunciation of the name Maryam, it is nevertheless specific to Christians, and we are commanded to differ from them and forbidden from imitating them in what is specific to them.
