We are using rke2 1.23 & intend to upgrade to rke2 >=1.26. Our question is around the use of self-signed k8s certificates. Is there a procedure in customers environment for doing following: (i) to update/change self-signed k8s certificates to commercial customer provided certificates & keep RKE2 cluster running (ii) to configure RKE2 installation with commercial certificates. Appreciate any suggestions/guidance. THANKS
