Maybe its an earlier model (9360 or 9365). For the 9370 Dell stated and different user reports confirm it, that the XPS 13 (9370) has the WIFI module soldered on board.
Some users on dell discussion portal reported also issues with the build camera.
For now, I will stay away from the 9370 model ...
One of the things that makes Dell my preferred vendor is that they publish service manuals: https://www.dell.com/support/home/us/en/19/product-support/product/xps-13-93...
I haven't looked through the entire guide, but there is no section for replacing WiFi, and the sections I've looked at don't appear to illustrate a WiFi module. Pretty good indication that it's an integrated component, I guess.
That said, I'm using a 9370 with Qualcomm Atheros QCA6174 802.11ac (Killer 1435) under Fedora (newer kernel, so I can't say much about how well it works under CentOS). I have not noticed any issues.
Beyond that, you can select which chipset you want when you order the laptop. I don't think there's any reason people should stay away from the 9370. It's one of the few laptops on the market whose manufacturer actively develops Linux support for the hardware.
