Hi, who know how to use vSphere CSI for new RKE clusters deployed by Rancher? to know, I created RKE cluster using Rancher and when I wanted to created RKE cluster, I choose vSphere provider among other providers (AWS, Azure, Custom and others), then I filled out few paramters including cluster name, node template, network and cloud provider!! in this part I am not sure what item should be selected (None, in-tree, external ) ??
