Hi,
you can use template override (for login page and module), but this is a bit complex, we recommend to hide the link with a simple CSS like this:

/* hide from login page */

div.login +div ul li:nth-child(2){display:none !important;}

/* hide from login module */

#login-form ul li:nth-child(2){display:none !important;}

You use a Joomshaper template, so you can create a file called custom.css with this code at /templates/shaper_helix3/css/
