Education LMS Theme customizations

I am using the Free version of the Education LMS theme (https://demos.filathemes.com/education-lms-pro/) for website development.

I am having two issues primarily.

  1. Is there any way to remove sidebars from pages?
  2. Default theme structure provides 4 sections in the footer. I want to make it to 2 sections only.

Obviously, I tried some methods to do this, and looks like editing core theme files is the only way. Did anyone did this specific editing or know what and where to edit?

Please let me know.
