I don't think that is currently possible. You can, however, filter your
build machines with a snippet like this in the operating system
declaration[1]. This filters away hosts that are not resolvable, but you
could adapt it to use some other predicate if needed.
```
(build-machines
(list #~(let* ((resolvable? (lambda (machine)
(false-if-exception
(gethost (build-machine-name machine))))))
(filter resolvable?
(list (build-machine
(name "example.com")
(systems '("x86_64-linux"))
(host-key "xxxx")
(user "offload")))))))
```
If you don't use guix system you can implement the filter logic in
/etc/guix/machines.scm.
