I think it’s perfectly acceptable for a DM to veto certain options that clash with their world, or have previously been established as verboten, or work with the player to come to a harmonious middle ground. If I say all elves wear masks in my world because they get bored looking at the same face for centuries, you either have to have your elf wear a mask, or come up with why they’re different and deal with the consequences.
But this seems to be none of those things. A DM can't just make your character for you (unless asked to do so). As others have said, I’d recommend just talking to the DM about this.
We’ve all known plenty of DMs that have more of an interest in just narrating a story than allowing free choice – it’s not always easy to let go of that at first, but ultimately working together to tell the tale is far more fun, as the PCs can take “your story” in wonderfully unexpected directions. Because really, it's everyone's story at the table.
