Need to configure NFSv3 over TCP
I am looking for the guide with how to configure NFS using TCP. At the moment I have configured NFS but no sure if it's using UDP or TCP.
No Events found!

You can not restrict the Datamover doing only nfs over tcp. It is doint NFS over tcp and udp, depending on the configuration of the client.
If you want to use NFS over tcp, this needs to be configured from the client, f.e. mount -o tcp ....
In the newer linux versions, nfs over tcp is the default.

Case in point to Peter's comment about it being a client side setting (Celerra and VNX both support NFS v3 via TCP or UDP) is that ESX/ESXi only mounts NFS filesystems via TCP. No special configuration required on the data movers to support this configuration as it is strictly client-side that controls which it uses.
I'm suspecting that the OP is looking to use VDM's with NFS v3 which is only supported with TCP (and not UDP).
