you could smoke it ... take dried jerky and put on a rack (you do not need to hang it ) and cold smoke it for about 30-60 min ... I just mentioned that you can do it . You could make drying process in smoker to begin with, but oven is way easier for temperature control. You can check other videos for cold smoking process.
I usually keep in some kind air tight container 2-3 weeks in pantry room ... or you can vacuum seal it - it should hold up to 2 -3 month no problem , but i would suggest to keep in fridge. Biggest problem for jerky is humidity and then high temperature ... you always can pack in to small zip-lock bags , squeeze air as possible and keep in a fridge ... check before eating :) - discard if it looks suspicious or smells funky ...
