How can I disable Nvidia Graphics or Use the Nvidia X server Settings?

I recently purchased a the XPS 15 with Nvidia GTX 1050. I installed UMate 16.04 the upgraded to 16.04.3. Then I Choose the Nvidia Proprietary Drivers. The problem is that I don't see any options in the nvidia-settings :
Here is the screenshot:

** Message: PRIME: No offloading required. Abort 
** Message: PRIME: is it supported? no 

ERROR: nvidia-settings could not find the registry key file. This file should
   have been installed along with this driver at
   /usr/share/nvidia/nvidia-application-profiles-key-documentation. The
   application profiles will continue to work, but values cannot be
   prepopulated or validated, and will not be listed in the help text.
   Please see the README for possible values and descriptions.

Also, This is the configuration panel for Additional Drivers:

Are there any ways to either get the Nvidia X server settings working or to disable the nvidia graphics (Because I am dual booting with windows and I use the graphics only for playing games)

Have you tried to switch back to Mesa/Nouveau (“X.Org X server” option), reboot, choose the nVidia driver again and reboot again?

Or tried to force the reinstallation of the package?

sudo apt-get install --reinstall nvidia-384

Hi, I am terribly sorry for taking this long to try it out. I actually just used the laptop with power cable connected and never worried much. However today I remembered that there was a reply and I tried it And it worked. Thanks

Here is the screenshot of X settings now
