   Validated using both v1.23.7-rc1+rke2r1 and master commit aa3027502617aa492628da505111107acecde0ce

   • Able to successfully set autodetection for both ipv4 and ipv6:

   $ sudo cat /var/lib/rancher/rke2/server/manifests/canal-values.yaml 
   apiVersion: helm.cattle.io/v1
   kind: HelmChartConfig
   metadata:
     name: rke2-canal
     namespace: kube-system
   spec:
     valuesContent: |-
       calico:
         ipAutoDetectionMethod: kubernetes-internal-ip
         ip6AutoDetectionMethod: kubernetes-internal-ip
   
   $ k get ds -n kube-system rke2-canal -o yaml | grep -A 1 -i autodetection
           - name: IP_AUTODETECTION_METHOD
             value: kubernetes-internal-ip
           - name: IP6_AUTODETECTION_METHOD
             value: kubernetes-internal-ip
   

   • Confirmed both ipv4 and ipv6 (and combined) services continue to work.

   $ kubectl apply -f https://gist.githubusercontent.com/aojea/90768935ab71cb31950b6a13078a7e92/raw/99ceac308f2b2658c7313198a39fbe24b155ae68/dual-stack.yaml

   • Confirmed default is still first-found:

   $ k get ds -n kube-system rke2-canal -o yaml | grep -A 1 -i autodetection
           - name: IP_AUTODETECTION_METHOD
             value: first-found
           - name: IP6_AUTODETECTION_METHOD
             value: first-found
