Want to put army level down grad

Lakaoum

Hi, i read a bit everywhere, that you can change the army level, for the skin on multiplayer. I dont intend to increase my level, in fact i would like to stay without some wargears skin with my orks.
I love see their skull and want them without helmet. But time after time, my level becomes higher, and all of them receive an helmet. I love my commandos without their gaz mask too. So how can i downgrad my army level, without purchasing another steam account and a new retributuion game (dont want to loose all the wargears). I have download the armaments of war, but it seems that it deliver only high rank army level. ANd how too install it (i have creat a repertory "mods" in gameassets, but doesnt seem to work.
