On resume, display log on screen, check box grayed out

The check box to disable showing the log on screen is grayed out, and not click-able.

How would I go about creating a GPO that would only allow a few PCs the option to disable this or let the end user using those PCs able to configure this setting.  I am looking to set the GPO at a computer level and not at the user level.  Any assistance would be helpful.

Thank you!
