I think what you said seems to be wrong. I checked the api documentation of vmservicescrapespec, and the relabelConfigs configuration should be under spec.endpoints. However, updating the configuration for stack-victoria-metrics-k8s-stack-node-exporter still doesn't seem to take effect.

Here is my stack-victoria-metrics-k8s-stack-node-exporter configuration:

I've updated my answer. Have you tried this as well?

Not ok. I see the configuration has been added.
