That would also work. Should the reload command handler also log then, so it is visible that there's a pending reload?

Another possibility is wrapping the Arc<SslAcceptor> in an AtomicBox (though that's not in the std lib, only AtomicPtr, but it should be easy to write one, (and there's an atomic_box crate)).
The advantage there being that the command handler could do the certificate loading and provide feedback to its client about whether it was successful, and it can just replace the pointer atomically.
