label not configured

Cluster information:

Kubernetes version: 1.20
Cloud being used: AWS
Installation method: installed independently with kubeadm
Host OS: centos7

Hi all,

I have just a small question:
Do the labels appear only on EKS managed kubernetes cluster or they are supposed to show up even on a manually installed kubernetes cluster on EC2 AWS instances?

And if they do, what is exactly triggering or preventing them from being set?

Thanks in advance
