is it possible to enable dualband or even 2.4 GHz on QCA9994? (Compex WLE1216V5-20)

It looks like it's really designed as either 2g or 5g. You could make
your own card up with both 2g/5g paths but you'd have to reload the
firmware/calibration data as needed to band switch. it wouldn't be
"automatic". :(

And I need the info, if and how is possible to enable dualband mode. If there is some physics like LNA or what ever missing, we can do this our self.
