Technically neutrals are required in every switchbox now, but if I were in your position I would just do it as described, creating a switch loop. The only reason the requirement for neutrals was codified was so that smart switches would be able to be installed everywhere (smart switches typically require neutrals). It's not for safety, that's the only reason. I don't imagine you or anyone will install a smart switch for you garbage disposal unit.

Thank you. It certainly would be cheaper to reuse the existing 12-2 that is already in place going from the switch instead of buying new 12-3.

Neutrals are not required in "every" switchbox now. They are only required for switches controlling lights. Even then, there are seven broad exceptions listed in the code.

Look up NEC 404.2(C).
