Domain through FreeDNS (or GoDaddy, or Route 53, or Namecheap, or whatever), and cert through Let's Encrypt? Both of those steps are pretty dead simple individually, though it's admittedly nice to knock out both at once. That's essentially what I'm doing for my own website, as one example. Granted, that's on a VPS instead of a home NAS, but the idea's the same; neither a domain registrar nor an ACME provider necessarily care.
