Since GFN doesn't allow you to reach the game files, and since there is no option to enable cheats in Bannerlord, you can't use cheats in GFN. But i think i found a way.
First, open your saved game (or start a new one)
Then open console with ALT+` (the button below esc)
Write "config.cheat_mode 1" in console and press enter. It should enable the cheat mode.
Now you can use cheats but you can't use cheats with CTRL+ALT combinations. GFN doesn't allow that. You can use the cheats with CTRL or CTRL+SHIFT combinations though.
