How to change the homepage of my blog completely?

When we install WordPress, the default page displays all the blog posts in reverse chrono order.

I know that I can go to Appearance >> Customize to change the homepage to display a static page and create a new page where all the blog posts will be displayed.

But this is what I want: The homepage should be completely my design! I have an index.html file (along with other folder like images, css stuff like that) with me right now! I want that file to be my homepage, and all the other pages on my blog to be displayed as the same-old WordPress way...

Is there any way to do that?
