Hello,
There is no way to change the link of the “REGISTAR NOVA CONTA” button, but you can create an alternative “Register” button.
First of all. navigate to Dashboard -> HTML blocks -> create button with the help of the “Button” element. Also, to the “link” field define the URL of the custom register page.

After that, navigate to Theme Settings -> Login/Register -> to the “Login text” area add this HTML block (check the below screenshot).

So at the end, you will have something like this: https://monosnap.com/file/iMk6AVKlEXOeaSHGL3GPDCbdggp5BR
