Header Struggle is Real

Site URL: https://www.classfivemind.com/freetraining

Does anyone know how to change the header on a specific page without it affecting the entire site?  I want to remove the entire header from a landing page I built, but keep it on all of my other pages.

I want to remove the logo and button from the Header on this page.

I want to keep the entire header like this on all the other pages.

Add to Page Settings > Advanced > Header

(If you use Personal Plan > Edit Page > Insert Code Block > Paste below code)

<style>
  header#header {
    display: none;
}
</style>
