Fibicom 5G module with Wifi6 Mini

I would like to get my BPI-Wifi 6 mini to work with a 5g module (more specifically the Fibicom FM350-GL 5G). So far I have seen that I would need to install additional packages via opkg (I am following a guide for the R3 mini: GitHub - def324/bananapi-r3-mini-guide · GitHub), however I do not have a wired connection in the beginning so I cannot install these packages. Are there any recommendations what I could do instead? Would it suffice to compile the following; would the necessary things be installed? GitHub - BPI-SINOVOIP/THG6500-TAX2-mini-OPENWRT-BSP · GitHub

Thank you in advance.
