Oops.. Comment 2 is a wrong PR... https://github.com/ManageIQ/manageiq-providers-vmware/pull/536
Based on Comment 5 and 7 I was able to: enable prototype.ems_vmware.update_driven_refresh: true, restart evmserverd, create a new storage profile in my VMware vSphere, and then drop into rails console to see StorageProfile.all as it listed all the storage profiles. Hence verified on Version 5.11.4.0.20200224230733_ab25bbf of CFME.
