Hey,
I think it is more of a question to Network adapters you are using. You should install proper drivers of the NICs. Usually with drivers installations RDMA will be enabled by default. As an example: https://www.chelsio.com/wp-content/uploads/resources/s2d-hci-quickstartguide.pdf
You can use the following article to verify RDMA connection. https://learn.microsoft.com/en-us/windows-server/networking/technologies/conv-nic/cnic-app-troubleshoot
In addition StarWind rPerf tool can be used to verify RDMA throughput. https://www.starwindsoftware.com/blog/starwind-rperf-all-in-one-free-tool-for-ensuring-the-maximum-performance-level-of-your-rdma-network-connections
