Remove Search icon/function in Header/Menu Axion Theme

I want to remove the search icon/function from Axion Organics Theme Version: 1.5.9

I have tried:
CSS fixes found on this forum ie. form.search-form { display: none; } etc
Header > Menu in Customizer has no disable the search

There are no search code in header.php or funtions.php

What i have is:

wp-settings.php:

require ABSPATH . WPINC . ‘/blocks/search.php’;
require ABSPATH . WPINC . ‘/rest-api/endpoints/class-wp-rest-search-controller.php’;
require ABSPATH . WPINC . ‘/rest-api/search/class-wp-rest-search-handler.php’;

search.php:

<?php
/*
Template Name: Search results
*/
get_template_part(‘blog’);
?>

searchform.php:

<form role=”search” method=”get” class=”search_form” action=”<?php echo esc_url( home_url( ‘/’ ) ); ?>”><input type=”text” class=”search_field” placeholder=”<?php esc_attr_e(‘Search’, ‘organics’); ?>” value=”<?php echo esc_attr(get_search_query()); ?>” name=”s” title=”<?php esc_attr_e(‘Search for:’, ‘organics’); ?>” /><button type=”submit” class=”search_button icon-search” href=”#”></button></form>
