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"
