Of course players are going to push boundaries. The DM can approve or veto any characters the players suggest for the campaign if it doesn't fit with what they are envisioning. I think generally Players and DM will compromise and meet somewhere in the middle for the campaign theme. If I went to a session zero and the DM already had everything planned out and was unwilling to compromise I wouldn't play.I would definitely make it drow-only. Players love to push boundaries whenever someone introduces an idea for a more themed campaign, and if you allow non-drow exceptions, you'll end up with a svirfneblin servant, a drider, a changeling that's passing for a drow, and a mutated elf with reverse albinism.
