You can use the `RMW_IMPLEMENTATION` environment variable: see https://github.com/ros2/ros2/wiki/Working-with-multiple-RMW-implementations

Note, however, that this will **only** take effect if you have built the node in a workspace that supports multiple RMW implementations. The pre-built binaries only provide support for the default, `rmw_fastrtps_cpp`.
