Yes, here is what you do:
1. Open the NVIDIA Control Panel - it is found in the lower right in the system control icons - you may have to click on the up-arrow to reveal it if it isn't showing in the system tray - it's a small green icon.
2. Once that opens, click on Manage 3D settings and then click the Programs Tab
3. Select the program you want to modify and change it to NVidia, do this for all programs that you want to use the NVIDIA graphics. But only do this for programs that absolutely need it as it significantly impacts battery life. I only use it for C1 Pro and Photoshop.
Here is a screen shot of what it should look like:
