Replace [MY_CONDITIONAL] with a condition that would apply to the page or pages where you wish to exclude the light box scripts.
is_page('prints') would apply to a page that has slug “prints”, or
is_home() && is_archive() would disable the scripts on your blog page and all archive pages. In reverse (notice the use of “!” meaning “not”),

How to do that depends on the page editor that is used on your site, and how much rights your user has. If you are using the WordPress core block editor, then you can place a HTML block at the bottom of your page/post content where you paste the above code. Other editors may provide similar content elements.
Or you could place the code snippet in an HTML widget and, if you are using Jetpack with the module Widget Visibility turned on, configure that widget to be active only on the parts of the site where you wish to disable the light box.
