Does every page on our site need content? Even if it has no search volume

We have put content on all the pages with keywords we want to rank for. There are some pages with no content but those particular pages have low to zero search volume as they are very niche products.

Does having pages with no content on them have a negative effect on the website overall? Should every single page be filled with content? Or can I safely leave these niche no volume products that would never sell anyway?
