Here's the problem: you can't change the hiring rules for more equity unless it applies to everyone equally. Otherwise you're just trading one arbitrary class for another. You need to basically destroy seniority and job protection for all, to make it fair. Furthermore, the people brought into replace the oppressive class must be held to a high standard so they don't repeat the offending behavior.

DEI agendas can only work if the displaced people (i.e. white males), see a genuinely better alternative rising in its place and are not asked to pay the price for their skin color and gender for their entire lives. I suspect white males would be far more accepting of DEI if it wasn't a lifetime penalty they felt they had to struggle against, but just a few years.
