A chromium project called Bromite exposes this flag[0], but I don't think it's ever been available on Desktop versions of Chrome (probably due to the likelihood of Schools, Enterprises, etc. getting mad if a user uses it to circumvent DNS blocks).
As per a comment by Eric [unknown surname] at Microsoft here[1], you can enable it on desktop chrome by adding the following to your chrome launch options:
This can easily be done persistently via Windows, but I'm not sure what it would take on Mac. The official Chromium guide for starting with launch options[2] only recommends opening terminal every time, which would mean it can't be easily ran on each launch with the shortcut/dock icon.
