module suggestion

https://www.amazon.com/dp/B01J705MTC?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1
just a fair warning about this product listing, the PCIE module is not included

this amazon product is a sim data to USB for internet via phone service, there is a version of the product on aliexpress as well however i only linking amazon because idk how people feel about aliexpress on here, the version on aliexpress is 9 USD.

the module idea that i was having was similarly to the antenna coming out of the back but for the device, the USB port on the device is in the front (antenna is in the back) making it perfect for that 4 hole module setup that you have already

Start with the linked Amazon product listing and the issue description, then inspect the existing rear-antenna and four-hole module design referenced there. No repository file, test, or entry point is named, and completion criteria for the proposed module are not defined; the design and scope need clarification before implementation.
