How to exclude

Hi, in the article https://euroclean.cz/clanky/jak-se-zbavit-zeleza-manganu-ve-vode/ a shortcode is inserted. After scrolling, the form pops up. It’s OK. But there is an excerpt from this article on the front page and a window will pop up on the front page of the site. How do I exclude a front page?
