No, i just looked it up. Easier.
Its the CiV4gameoptioninfos.xml in XML , Gameinfos folder in the mod-folder of FFH2 0.32. (so you should just be able to enter it without another software.

I did use since i can't open all the xmls sadly so i wrongly presumed i couldnt and just used something else.)
Change Adventure Mode to visible and turn it off ingame by entering a custom game-screen and then start said game. You can make it invisible again afterwards if you like since it remembers you unchecked that option.
PS: Ill pass on the cokie though.
