Hi Erim, this is possible. You can edit header.php directly buy you should do this by creating a child theme https://codex.wordpress.org/Child_Themes
Open header.php and find this line
<!-- Show cpt-bootstrap-carouselplugin if active, show header image if it's not -->
<?php if (function_exists('cptbc_columns_head') ) { ?>
You will need to add a conditional to the if statement that checks if it is the front page being viewed, if it is then show the slider, if not then don’t show it.
Change those lines to this.
<!-- Show cpt-bootstrap-carouselplugin if active, show header image if it's not -->
<?php if (function_exists('cptbc_columns_head') && is_front_page() ) { ?>
If you want the header to show on other pages then it will need to be modified but I can help with that too.
Here is a pastebin link to the entire header code with the changes already added.
