No problem:

1. Get a copy of nixpkgs: `git clone https://github.com/NixOS/nixpkgs`
2. Save the [snippet](https://discourse.nixos.org/t/nixos-stable-wont-boot-from-usb-on-xps-7390/4776/5) to `iso-image.nix`
3. Adapt the first line of the script that it points to location of `nixpkgs` (from step 1)
4. run `nix-build iso-image.nix` to build the image.
5. In the folder `result/` you will find the iso-image, which can write to a USB stick with `dd`
