Note that the VCF Compatibility Guide only applies to old VMware Cloud Foundation 2.3 versions.
Starting with Cloud Foundation 3.0 any vSAN Ready Node can be used as hardware. To find supported hardware for Cloud Foundation pick any compatible vSAN Ready Node using the vSAN Compatibility Guide and also check minimum hardware configuration requirements from the Cloud Foundation Documentation.
However, looks like NetApp HCI is not a supported vSAN Ready Node. So the first step is to talk to NetApp and ask them when their systems will be supporting VMware vSAN. Then you can use them for Cloud Foundation.
