Remove Sidebar From Static Front Page

Hi! I am currently building a website, using Leather Diary. I would like to know how to remove or hide the sidebar from the static front page, while keeping it visible on subsequent posts. I did create a child-theme, to make editing possible. Please advise the best way to resolve this issue. Thank you in advance.

(I did not link the website, because it cannot be viewed. I prefer to perfect the back-end, before going live. However, I will add the link once it is published, so others can reference the change).
