LTE / 4G / 5G QMI support

Hello All,

I am looking to build a ipfire box with a mini pcie WWan card 4g to begin with then 5g later as the 5g network expands in my area. My question is anyone working on adding QMI support currently? If yes once my hardware arrives I am happy to help. If no can someone point me to any doco for getting started with implementing this feature.
