Drop kubernetes node labels

[UbiquitousBear]

Hey, I'm trying to drop kubernetes node labels from being sent upstream, however, I'm unsure what to use as the source. I've tried using __name__ however this is not effective. I assume __name__ is incorrect as that applies to the metric name, so what am I meant to be using?

relabel_configs:
 - source_labels: [__name__]
    regex: (.+)kubevirt(.+)
    action: drop

The K8s node itself has labels such as: kubevirt.io/schedulable=true which I'm trying to filter out, where the label contains the word kubevirt.

It looks like I can use the labeldrop directive:

- regex: (.*)kubevirt(.*)
  action: labeldrop
