Yes, it is possible and the README mentions that the plugin has been tested with EFA provider. Here is a getting started doc on EFA over P3dn which uses the plugin: https://docs.aws.amazon.com/AWSEC2/latest/UserGuide/efa-start-nccl-base.html and https://docs.aws.amazon.com/dlami/latest/devguide/tutorial-efa-using.html

Hi,
Is there any code I can refer to that uses libfabric RDM endpoint primitive? (i.e. fi_send) Also I found there's code in libfabric repo about FI_HMEM. Does it mean I can receive data using efa to a registered cuda memory directly with something like fi_mr and fi_msg?

This plugin repository uses fi_tsend for libfabric RDM endpoints. Yes, with FI_HMEM, you can use cuda buffers directly. This plugin also has code for that.
