In "Having a specific conference for women in computing is definitely a DEI concern" I take concern to be the noun, Mirriam-Webster (1a) or (2) has something that relates or belongs to one : affair, from the context this would seem to be the definition that fits: DEI relates to such a conference, they're interested in it, rather than definition (1b) an uneasy state of blended interest, uncertainty, and apprehension which would lead to "concerning" but makes no sense in the context, as you note.
