You do not need to do anything special. iMessage will automatically use the current preferred data network to send messages. If you are connected to WiFi then that will be used preferentially. Cellular data will be used if WiFi is not available. This choice of data networks is always automatic on iOS devices.
About the only thing that can change the normal iOS decisions of which data connection to use is the "Wi-Fi Assist" feature.
