Actually you don’t need to do so much to deactivate Esx default HUD. Go to es_extended Folder, and look at row 9 than you must change it from
Config.EnableHud = true
to
Config.EnableHud = false
Now Esx Hud is deactivated and you can install another one i.g.
Trew HUD or Enhanced HUD but you need to do a some additional adjustements to remuve huger and thirst bars (we can do it in another post or you can watch video that I have postet at the end (it will be explained there). And for Trew Hud you need some additional adjustements depending on the Esx version which you are useing.
This is the video: 😉
