Disable ULPS: What is the difference between EnableULPS and EnableULPS_NA?

Hello,

or several years now, ULPS has to be deactivated, especially on laptops with dual graphics, otherwise a black screen is displayed for 1-2 minutes every time windows boots.

In the registry the value for "EnableULPS" is set from 1 to 0.
However, what function does the value "EnableULPS_NA" have?
Some write that this should also be set to 0, others clearly mention that it should be left alone.

Does anyone know anything more about the function of "EnableULPS_NA"?

Thanks and greetings,
Martin
