I got Jaeger figured out - I’m sure Grafana is the same. I was missing the enabled arg (–set tracing.enabled=true):
helm template --name istio --namespace trace helm/istio/install/kubernetes/helm/istio --set tracing.enabled=true -x charts/tracing/templates/deployment-jaeger.yaml -x charts/tracing/templates/pvc.yaml -x charts/tracing/templates/service-jaeger.yaml > helm/jaeger.yaml
