Issue with Rancher Webhook Configuration on Gardener-Managed Kubernetes Cluster

I’m attempting to deploy Rancher on a Kubernetes cluster managed by Gardener. I’ve encountered a problem with the validating webhook configurations installed by the rancher-webhook pod.

Specifically, the failurePolicy for within the kube-system namespace is set to Fail. However, this configuration is not permissible within my Kubernetes setup.

As a temporary fix, I can manually edit the webhook to exclude the kube-system namespace, but this change is overwritten whenever the webhook pod restarts.

Does anyone have suggestions for a more permanent workaround that would prevent the kube-system namespace from being impacted by the failurePolicy of the Rancher webhook?
