MC7455 only have an MBIM interface, how to switch to QMI mod

Hi, All

I have MC7455 card, which only have an MBIM interface, and all AT ports are switched off by default. GPS is also switched off and there are no standard means to enable it!
I want to know is there any method to switch to QMI mode, or enable all of the AT ports and GPS ports?

Thanks

Fupan
