Traefik and k3s, tcp/udp routers


I have deployed traefik in k3s and it works just fine, but now I want to use it for tcp and udp routers as well, how do i configure it for that? I'm guessing I have to redeploy it? Do I loose all existing http routers if i do that?

Also, I don't use LetsEncrypt (can't, catually, my k3s is not reachable from the outside), so I have successfully replaced the defauld certificate with a wildcard certificate - but when I reconfigure traefik for the additional tcp/udp ports I want to use, can I just remove the three parameters for letsencrypt?
I mean the three "--certificatesresolvers" entries, my yaml file is here: TraefikDeployment.yaml ยท GitHub
