That's more in the marketing campaign so far (though there is a scene where they alter Nick Fury to act like a sappy idiot until Captain Marvel puts him in his place in an attempt to make Captain Marvel look like a no-nonsense badass). The filmmakers are making a big deal about how this is going to break glass ceilings (even though films have been kind to women for decades; two years prior the film for feminist icon Wonder Woman was a smash hit).
There's also the "Take girls to see Captain Marvel" go-fund-me campaign https://www.geek.com/culture/crowdfunding-campaign-raises-money-for-girls-to-see-captain-marvel-1770058/ ; unnecessary virtue signalling. There's already lots of works with good messages for girls. Also, an example of filmmakers making a difference is how the filmmakers for Alita: Battle Angel gave bionic arms to a teenage girl who's a double amputee https://www.yahoo.com/entertainment/alita-battle-angel-filmmakers-give-new-bionic-arms-young-amputee-154443064.html ).
Finally, there's Brie Larson's (the actress playing Captain Marvel herself) repeatedly denouncing white men (half-ironic since she's a white woman too) and saying she doesn't want too many in the interviews and - maybe - the audience. https://www.foxnews.com/entertainment/brie-larson-doesnt-want-captain-marvel-press-tour-to-be-overwhelmingly-white-male https://www.reddit.com/r/SJWstories/comments/aqb9pv/woke_captain_marvel_brie_larson_hates_white_men/
