Naming react website url in github pages

While deploying my create-react-app website to Github pages, one of the steps involves setting up the homepage in package.json . 

{
...
"homepage": "https;//GithubUsername.github.io/reponame",
....
}

 However, is it possible to set this to only http://GithubUsername.github.io/ ?

See our help docs on how to set up HTTPS support for your GitHub Pages site.

Let us know if you have any questions.

Not what I was looking for😅. The answer to my question is to deploy on the “master” branch, with the name of the repository as username.github.io
