After deploying RKE2 cluster via Rancher 2.7.1... I want to change "Cloud Provider to External" I can do that by edit Yaml and add

cloud-provider-name: external

under

machineSelectorConfig

. This appears to work... My question with this is, do I also need to include

disable-cloud-controller: true

? If so, where does this get added in YAML or the GUI?

If you are deploying your own cloud provider... yes, set

disable-cloud-controller: true

Its set in the yaml on each master node.
