There are plenty of books on the 'rules' (except for grammar, they're more guidelines than rules) of writing, just like there are books and other material on how to draw, paint, do pottery, watercolor, etc. Just because you can break a rule doesn't mean it isn't a rule or that it's there for no reason. Rules in all creative arts exist because they are
usually a good idea to follow unless you're experienced and you know how to bend, break, or subvert the rules to make a better work of art.
Grammar related rules are usually better off followed to the letter. If you can't spell, use punctuation correctly, or structure a paragraph well then people won't be willing to even finish the first page, let alone the first chapter. 'Rules' regarding scene composition, chapter structure, and story structure all sort of open up more as you increase in scale to allow the author more freedom to do what they want.
Other elements, such as style, word choice, overall language complexity, and others are mostly free from rules.
In terms of prose, there are many books on grammar, style, structure, etc. Want a book that teaches you how specifically how to write engaging 'scenes' in your work? They have those. Not sure how paragraphs and sentences and semicolons work? They have books for those too. Looking for tips on improving your style? Yup, they have those. Want to focus on action in your scenes? Or tension? Or drama? Books on all those topics exist.
