Yes, I seem to recall that DEBUG means optimizations enabled, but debug
code (such as DEBUG(), ASSERT(), DEBUG_CODE(...), ASSERT_EFI_ERROR())
included. Indeed NOOPT seems to be what edk2 assigns generally to the
build you'd like.

A NOOPT build target for OVMF (and more generally for GCC toolchains I
guess?) should be possible, likely even welcome, I believe. If only
someone contributed such BaseTools patches. :)

('git grep -e NOOPT --and -e GCC -- BaseTools' returns no hits.)

Thanks
