Yep. But, this can be undone for a single driver with an override like:
Path/To/Driver.inf {
<BuildOptions>
MSFT:*_*_*_CC_FLAGS = /UMDEPKG_NDEBUG
GCC:*_*_*_CC_FLAGS = -UMDEPKG_NDEBUG
}
But, note that this will not undefine MDEPKG_NDEBUG for libraries used
by the driver. So, you might need to specify a similar override for a
library's .inf.
