Hi RVillani,
What type of laptop are you currently using? If you have an Nvidia card in the laptop you should be able to change this in a couple of ways.
-
Optimus technology. You should be able to specify the GPU that you would like to use.
-
Nvidia Geforce Control Panel. You should have an option to choose how you want the GPU to be used. Should be similar to this setup here: https://support.lenovo.com/us/en/documents/ht078706
