That’s not really possible. ARM doesn’t have _any_ kind of standard boot mechanism across boards, except for EBBR which is (mostly) only adopted on servers. See: [Planning for a better NixOS on ARM (and other non-x86\_64 systems)](https://discourse.nixos.org/t/planning-for-a-better-nixos-on-arm-and-other-non-x86-64-systems/15346)

You can probably add it to [the `disabledModules` list](https://nixos.org/manual/nixos/stable/#sec-replace-modules) (note, that section is titled “replace modules”, but you don’t actually have to provide a replacement).
