Whatever comes with should work mostly fine, whitelist unlocks are for those didn’t option a WWAN. All WWAN modems are same, usually they have 3-5 serial ports for modem control, data, debug, and NMEA. My hunch is your ttyS2 takes “GPS enable” command and it’ll start murmuring it on ttyS4.

None of the TTYs that Windows exposes will even let me connect (access denied error even as admin) and there is no Linux driver, or maybe there is now with very recent kernels?[0]. It would surprise me if it worked well but I will spend some hours to find out soon. Intel/Fibocomm don't provide support for their modems except to OEMs afaik and I don't see any mention of successful connection under linux w/ my modem. (Fibocom L860-GL/Intel XMM 7560) around the internet. I have tried with some other LTE modem (model forgotten) in the past and I wasn't able to see it under Windows or Linux at all.

Use USB-Mode.
[0] says it also supports MBIM which is supported ootb with ModemManager and somewhat recent kernels. If your BIOS does not allow this, you probably need to tape over the PCIe-Pins with some non-conductive tape.
