Hello,
the way I’ve made static a static home page is by first creating a page in the “Pages” section in your Dashboard. Once you’ve created a page (e.g. ‘Home’) you can then go into your appearance section in your Dashboard and you will see a Customize option.
In there you will find an option titled “Static Front Page”, there you will fine 2 choice,
1) your latest posts, and
2) static page
Once you select a static page, you will be shown 2 drop down menus, one for Front page and one for Posts page. There you can select your newly created ‘Home’ page as your front page, and if you’ve created a page just for posts, you may select that for the Posts page
Hope this helps!
Cheers!
