    Additional options that may enable you to compare the performance of each video:

    a) Turn off using the respective control panels
    Nvidia Optimus
    AMD Switchable graphics

    b) Open the BIOS > some computers have settings that can be turned on /off

    c) Modify / uninstall drivers

    Hello LevGorinshteyn

    Yes, you can use the next:

    Script for Disabling :
    pnputil /disable-device "InstanceID"

    Script for Enabling:
    pnputil /enable-device "InstanceID"

    To find instance ID of your discrete card you can access Device Manager in Windows and from the properties of the Adapter, Details Tab, the value is on the "Device instance path"
