I believe it has already been done for you.
The LM78L05 regulator that supplies 5v to the IRF510 gate bias pots is in turn powered form the TX 12v rail.
That TX rail is shut down during receive by the TR relay, goes to zero volts, so gate bias will also do so.

I think Jerry has a much simpler idea -- just
find a way to disconnect the gate bias during receive.
