Customization of student registration popup modal

Hi guys,

How can I customize the student registration popup modal? By default when I click on the “Dashboard” modal with login fields comes and text behind is changed to “Please Sign-In to view this section”. I didn’t find answers in documentation, but only a shortcode for student registration page.

I want to change some stuff on modal, for example, do delete a line of text “Don’t have an account yet? Sign up for free”. Also, delete the section beneath the “Log in” button. How to achieve that.

Is it possible to show only the modal for student registration after clicking on “Dashboard” without changing a page with the text “Please Sign-In to view this section”?

I hope you understand my struggles. Thank you for your time in advance.
Nikola
