There have been minor updates by the publishers. Generally these are spelling updates, or changes to the punctuation. But there have been a lot. Each publisher generally changes something or other. Rick Norris has compiled a huge book on these, called "Facts from 400 Years of KJV Editions: Do We Use a 1769 KJV?"
You can also purchase fascimile 1769 Bibles (or 1611s) that are photocopies, so definitely with no revisions. Example: https://greatsite.com/facsimile-reproductions/1769.html
