That’s not how DEI programs operated at places I’ve worked. They were more about expanding candidate searches to look for high quality people at other places than we’d been looking, reducing alcohol at company events etc
As a vegetarian, I really struggled finding good non-meat options though.
Reducing or removing alcohol at social events is not done for "inclusion reasons" but for straightforward legal liability reasons: a drunk employee often has poor impulse control and may do or say shitty things that they wouldn't if they were sober, and with some probability this results in lawsuits against the company. No drunk people at social events -> fewer lawsuits.
