How to remove all secrets from a service

Not a bug!

¿How to remove all secrets from a service? Without losing labels, networks, anything.

In docker tools it's easy: docker service update --secret-rm SECRETS_NAME SERVICE_NAME

Docker-client I not know how to do it

ServiceSpec spec = ServiceSpec.builder()
		        .name(service.spec().name())
		        .taskTemplate(service.spec().taskTemplate())
		        .mode(service.spec().mode())
		        .endpointSpec(service.spec().endpointSpec())
		        .updateConfig(service.spec().updateConfig())
		        .build();

docker.updateService(service.id(), service.version().index(), spec);

¿ Secrets is an ImmutableList ?
