I am able to explore the Archer C9v1 bin file with 7zip file manager. Would it be a simple matter of unzipping this file then copying over some ko modules and then re-zipping this file back up and uploading it the router? The ko files work after testing them but now want to make them permanent in the firmware itself so I can load them on boot.

In short, no.

In not short aka long: you need to find out how the firmware file is being packed (possibly with compression)! Maybe reading the source codes? The Makefile? Smile
edit:
The same method applies to motherboard BIOS. DD-WRT is the BIOS of routers in some ways? Or is it?

Thanks for the info but I already tried those un/pack utilities and they threw undecipherable errors. I will just load the batman-adv.ko modules via USB although would prefer it in the firmware itself. Since the C9v1 is the same hardware as the R7000 I was able to just extract and copy over the batman-adv.ko file and it loaded fine on the C9.

Oops, these are for nvram backups not firmware.

If you have compiling expertise you can compile your own builds:
