Hello @lbrites,

The option to change the background image of the Call to action section is not available within the theme.

However, we will provide the custom CSS using which you change the background image of CTA section.

For this go to Admin Panel > Appearance > Customize > Additional CSS and paste below given CSS.

#background-image-section {
    background-image: url(YOUR IMAGE URL);
    
}

Here replace the text with your image URL.

Hope this helps.

Best Regards!!
