a) For `nixos-rebuild` you can set

{ nixpkgs.config.allow${up reason} = true; }
in configuration.nix to override this.
b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add

{ allow${up reason} = true; }
to ~/.config/nixpkgs/config.nix.

You can install it anyway by whitelisting this package, using the
following methods:
a) for `nixos-rebuild` you can add ‘${attrs.name or "«name-missing»"}’ to
`nixpkgs.config.permittedInsecurePackages` in the configuration.nix,
like so:
{
nixpkgs.config.permittedInsecurePackages = [
"${attrs.name or "«name-missing»"}"
];
}
b) For `nix-env`, `nix-build`, `nix-shell` or any other Nix command you can add
‘${attrs.name or "«name-missing»"}’ to `permittedInsecurePackages` in
~/.config/nixpkgs/config.nix, like so:
