TL;DR

1. set the keyboard to Windows mode using the side switch

2. hold Fn + X + L for 4 seconds to set the function key row to fn mode

3. ensure the hid_apple module is loaded

   sudo modprobe hid_apple
   
   # load at boot
   echo 'hid_apple' | sudo tee /etc/modules-load.d/keychron.conf
   

4. configure the keyboard's fn mode:

   echo 0 | sudo tee /sys/module/hid_apple/parameters/fnmode
   
   # load at boot
   echo 'options hid_apple fnmode=0' | sudo tee /etc/modprobe.d/keychron.conf
