    dual graphics in laptop

    I have an asus TUF laptop with amd integrated and amd discrete graphics. I want to know if there is a method to fully disable the discrete graphics in the laptop for power saving. or.. Maybe the discrete graphics if there is no graphic workload is almost down and off?
    I am asking because in windows I get 10 hours of battery and in linux less than a half. I don't know the cause yet, but I don't think the problem is in the CPU..

    Okey, thanks for your answer, I was having problems with battery drain in linux and I didn't know if the problem was de CPU, the Igpu or the Dgpu. The laptop was an asus fx705DY with ryzen 5 3550H and rx560, in windows I have 10 hours with power usages in idle of 5W aprox and with Linux the battery give me 3-5 hours only, with idles power usages of 12 W. I returned it because it was so weightned but I am going to buy the same model with 15 " so.. I am interesting in find the cause of the battery drain to use linux like the main OS
