Blog Category page – delete info

Hi, I created a news-page, but I dont want to see the information about author, date etc. How can I remove that? https://nieuwburgen.nl/category/nieuws/ When you open a blog page, I also want to delete the 'related news items' on bottom of the page, or only detele the category name in the related posts. Is that both possible? I prefer the last option. Thanks!
