Wonder how "disabled" it has to be?
Or maybe it could be transferred to another organization that might meet the requirements of the state?
Maybe something like roaring camp railroad, or niles canyon.

So they don't want it to be used in CA, but are only selling it in CA. Hence the engine must be disabled.
i don't know if this engine has glow plugs but there is likely a similear cheap part that if removed disables the engine.
