Unfortunately I don't believe such a device exists.
The reason for this is LTE WWAN cards are almost exclusively USB 2.0 based.
The protocol is simpler and cheaper to implement than PCIe, and since they don't need the bandwidth why bother.
A few searches only turn up these form factor cards.
You may be able to find a card that has a USB to PCIe converter chip for an mPCIe/m.2 slot.
A properly designed card would have a PCIe switch with a USB chip to provide both PCIe and USB to the mPCIe/m.2 slot.
It's still a waste of a 1x slot's bandwidth, let alone a 4x slot.
5g will require USB 3.0 or PCIe to provide full speed, but those devices don't exist in the consumer market yet.
