MOSFET source to drain Current

Similar kinds of questions have been asked before it but they don’t clarify how one can use this aspect in circuit.

I’m aware that a MOSFET is a bidirectional device and in one direction current can flow from Drain to Source upon giving a gate pulse of sufficient amplitude & through body diode in reverse direction.

Now, Lets say I have connected Drain to higher than Source and current is flowing through the body diode, But at the same time I want to turn on the MOSFET Source to Drain channel to allow current to flow from the channel from source to drain parallel with body diode. Is it possible ? In this case what should be the Gate potential will it be higher with reference to drain or source? I’m new to this domain & confused. Please Help!
