Though, it looks like overlaying with the patch doesn't resolve this issue either so more investigation may be necessary.

Ran with build instead of switch by mistake, this overlay does actually resolve the issue.

nixpkgs.overlays = [ (final: prev: {
	racket = prev.racket.overrideAttrs (old: {
		patches = old.patches ++ [ ./force-cs-variant.patch ];
	});
} ) ];
