Is there a way to override mandatoryFeatures = [big-parallel]?

[n8henrie]

I'd like to be able to compile the installer ISO on my M1 Mac from aarch64-darwin.

It seems like a simple task -- nix run nixpkgs#darwin.linux-builder and then nix build --builders 'linux-builder aarch64-linux' -j0 .#packages.aarch64-linux.installer-bootstrap.

Unfortunately, the kernel requires big-parallel, which isn't enabled by default in linux-builder.

I could use nix-darwin to configure a builder that supports big-parallel, but AFAICT that then enables a launchdaemon that runs on boot and will be consuming system resources all the time, when I'd rather just run nix run nixpkgs#darwin.linux-builder manually for those rare cases of wanting to cross-compile for aarch64-linux from aarch64-darwin. I presume it would require even more effort for non-nix-darwin users.

It seems that this is probably resulting from somewhere deeper in the kernel-building tooling via requiredSystemFeatures, as I don't see it specified in this repo; is there a way it could be disabled for the asahi kernel to allow easier building from aarch64-darwin? My simple attempts at an override with overrideAttrs or overrideDerivation don't work.
