Rancher TLS version

I have installed Rancher 2.4.6 with a letsencrypt SSL certificate.
e.g. helm3 install rancher rancher-stable/rancher --namespace cattle-system --set hostname=some.hostname --set ingress.tls.source=letsEncrypt --set letsEncrypt.email=some-email

I noticed that it allows TLS versions 1.0 and 1.1.
I would like to be able to specify the TLS version to be used (e.g. 1.3).
Is there a way to specify this? Maybe some helm chart option?


The helm installation of Rancher just creates an ingress rule; what options it offers on connection are going to be up to the configuration of whichever ingress controller is installed in the cluster.

Rancher is deployed on a k3s cluster, using the default traefik ingress.
I found a reference here to traefik minimum tls version: https://docs.traefik.io/https/tls/
Still I have no idea where this is set in the k3s cluster.
Can you please give me any more pointers?
