This should be possible by not specifying this in the search paths, and the base domain:

https://docs.rs/trust-dns-resolver/0.22.0/trust_dns_resolver/config/struct.ResolverConfig.html#method.set_domain

or search paths:

https://docs.rs/trust-dns-resolver/0.22.0/trust_dns_resolver/config/struct.ResolverConfig.html#method.add_search

It looks like we don't expose a way to clear those settings, but you could set a domain of . that would effectively do that (I think).
