That's the thing, DEI advocates generally don't advocate for diversity quotas or hiring targets and such practices are not common. For example, when I went through the DEI portion of interviewing training we were explicitly told that we were not allowed to hire people of a certain group in order to try to improve diversity.

If your mission is to promote diversity and your job is to hire people, you are either increasing diversity hiring or you aren’t completing your mission or job.

You can find reports of hr employees and lawsuits involving major companies and universities to the contrary, where there were quotas and discrimination, implicit or explicit.
