You can create a landing page and design it as you want.
And, set that as home page.
On that home page you can add the links to the other language pages.
It needs some HTML knowledge which is out of support scope.
You can consider https://wpml.org/contractors/ if you not sure about.
or use this option hidden link and here also you have to define a HTML page.
Let me know if you need anything else regarding this within the support scope. 🙂
