Configure the "authority" attribute.
For gRPC requests this is the authority() field in the grpc::ClientContext. This configures the :authority pseudo-header in the HTTP/2 request. https://datatracker.ietf.org/doc/html/rfc7540#section-8.1.2.3
For REST-based services using HTTP/1.1 or HTTP/1.0 this is the Host header.
Setting this option to the empty string has no effect, i.e., no headers are set. This can be useful if you are not using Google's production environment.
