Connecting to RM502Q-AE via PCIe

Hi there,
We are trying to integrate the Quectel RM502Q-AE module via PCI with a raspberry pi 4 compute module. Unfortunately it looks like the modem doesn’t use the correct kernel module (See the output from lspci -v). It is shown correctly via lsusb (See output from lsusb).
We configured the modem with the following AT commands:
Output from “AT+QCFG=pcie/mode": +QCFG: “pcie/mode”,0 OK
Output from "AT+QCFG=data_interface”: +QCFG: “data_interface”,1,0 OK

Output from lspci -v:
