Looking at that article, it looks like for "Professional" degrees, it was about 25% white and 40% Asian. The "White 6%" figure came from a decrease in white workers in low-skilled roles and a massive increase in Hispanic people in those same roles.

Given that many DEI programs specifically focus on "high skill" roles (like software engineers), it's unlikely that DEI accounted for this disparity while massive numbers of black and hispanic people being hired for low-skilled jobs had a larger impact.
