On a second note, I don't like this.
We don't support enum variants (fields) with the `api` macro, so I would 
have to create
a struct containing `mode` and `secureboot`. That again implies that 
bios + secureboot is
possible, which is not.
But I get your argument about consistency between products, so if we'd 
go that
way, I'd send another patch with the requested changes...
