Is it possible to enable RDMA nic manually in the CVM after manually passthrough the Mellanox network card to CVM in ESXi?

It is not enable RDMA during foundation and the cluster is created.

After passthrough the NICs to CVM in ESXi, I checked that the NICs are already in the lspci result but can not enable RDMA in Prism.

So if it is not possible, that means if the cluster is created without RDMA enabled. there is no way to re-enable RDMA except re-foundation the cluster?
