Hi Bluebit,
How do you mean hide/disable Display name for WC account page, can you clarify your question?.
Also you must understand that the way WooCommerce functions are presented in the front-end depends on factors like the theme, and each theme has their different elements.
It will be of great assistance if you can provide us a screenshot of what you want to hide and also a link to the page. only then can you get a custom code to do the job.
