Change url registrate form using hooks

Hi,

I need some help when the following functionality.

I want to change the register student page / instructor, replacing the default pages with my pages created with Elementor plugin. Furthermore, I try to change the pages using the settings of tutor, but for some reason the change aren’t applying. In past days I read another forum that says like there’s an incompatibility with tutor and Elementor. Reading that, I decided to replace the URL directly in the util.php code. But, if an update coming, my custom code will be overwriting. So this bringing me to my question: There is a hook or something that let me applying in a different space (like code snippet) my changes and not lost my code?

The scenario that is causing problems is the following:

I configure that users can’t buy a course if they are not register, so every time they see a course and want to buy it clicking in the add cart button, the tutor login pop up will appear, and if the user click on Register now, the user will be redirecting to the default page of tutor and not mine. And well, this problem can’t solve with the tutor settings.

I wait for your answer.
