Change Traefik CRD

Hi all,

K3s is installed with Traefik as default router.
I've installed Kubernetes-dashboard with TLS Certificat. Unfortunately it doesn't run and as I read that the value insecureSkipVerify should be enable.
How should I proceed?
Create a Traefik CRD for kubernetes-dashboard or change one?
or re-install Traefik?
Here're my CRD list:

# kubectl get crd
