There's no X setting to directly control it. The NVIDIA driver uses the
overlay queue if possible. IIRC the driver documentation has more
detailed information about when it can be used. The most likely reason
it's not available is that you have the composite extension enabled in
the X server (another easy to trigger case is if you already have
another window using the overlay). Try adding the following to your
xorg.conf:

Section "Extensions"
Option "Composite" "Disable"
EndSection
