Assuming you setup xserver.videoDrivers correctly, you can try one of the solutions in the following: nixos: hardware.nvidia.package option for selecting nvidia package by FRidh · Pull Request #49703 · NixOS/nixpkgs · GitHub or https://github.com/NixOS/nixpkgs/issues/51768. Though for the unstable branch, it should’ve already reached a good driver version.
