Disable home_url rewrite with WPML plugin

Disable home_url rewrite with WPML plugin

I'm using the WPML Wordpress plugin to translate my website. My default
language is French. When I'm in a translated page, the home_url() is
rewrite with the current language. How can I disable this rewrite so my
home_url() always redirect to the french homepage?
Translate page url : http://www.mydomain.com/en/test/
Actual home_url() : http://www.mydomain.com/en/
Desired home_url() : http://www.mydomain.com/
I've already tried these solutions :

Sorry for my poor english and thanks for the help! Let me know if I need
to provide any other information.
