No, the thing about RDMA is that it significantly lowers latency and allows for copying of data without involving the cpu. If you use RoCE, you need advanced network switches that support PFC, ECN, DCBX that allows for lossless ethernet with the ability to pause frames to see any benefit. While lossy RoCE do work on newer generation of network interfaces, it comes with quirks and may not be any faster than TCP.
