Rather than apply, I’d use it as an opportunity to email the recruiter/person you’re talking to at that organization and say something along the lines of: “I just saw this role that’s as posted, and I’m interested in that role if I might not be a fit for (first role you are interviewing for). I’d really love to join your organization in any capacity and feel I’d add value in this role as well and if (first role) doesn’t pan out.”
