Yes, the radio modules can be potted. But you should avoid getting potting material inside the module shield can, as this may affect the circuit operation. In particular inductors are susceptible to detuning if the potting material gets inside the module. This could detune filter components, so very careful tests must be done after potting, to verify proper operation. In particular output power, harmonics and spurious emission should be tested. Using a potting material with less viscosity will reduce the risk for filling the shield can cavity with potting material.
