How to deregister a jquery version for a specific page?

Haven’t tested it but this should work with small tweaks:

function deregister_script_page_createit() {
    if( is_page( 42 ) ) {
        wp_deregister_script('jquery');
    }
}
add_action( 'wp_enqueue_scripts', 'deregister_script_page_createit' );
