Assigning to a specific TAG or CATEGORY a custom sidebar

hi
is it possibile to assign to a specific category or a specific tag only (i.e. in our case https://www.greenplanner.it/tag/greenict/) a custom sidebar?

how can we do? and is it possibile to assign also a custom header (with a dedicated adv position)?
thanks

to better explain what I need… I already created a specific tag-ID.php file for the tag I needd to customize

in this code… how can I indicate to use a specific header and a specific sidebar?

<?php
get_header();

$current_tag_name = single_tag_title( ”, false );
?>

<div class=”td-container td-category-container td_category_template_1″>
<div class=”td-container-border”>
<div class=”td-pb-row”>
<div class=”td-pb-span8 td-main-content”>
<div class=”td-ss-main-content”>
<div class=”td-page-header td-pb-padding-side”>
<?php echo tagdiv_page_generator::get_breadcrumbs(array(
‘template’=>’tag’,
‘tag_name’=>$current_tag_name
)) ?>
<h1 class=”entry-title td-page-title”>
<!–<span><?php esc_html_e(‘Tag’, ‘newsmag’); echo ‘: ‘ . $current_tag_name ?></span>–>
<span><?php echo $current_tag_name ?></span>
</h1>
<?php //the category description
$td_tag_description = tag_description();
if (!empty($td_tag_description)) {
echo ‘<div class=”td-category-description”>TAG: ‘ . $td_tag_description . ‘</div>’;
}
?>
</div>

<?php
get_template_part(‘loop-archive’ );
tagdiv_page_generator::get_pagination();
?>
</div>
</div>

<div class=”td-pb-span4 td-main-sidebar”>
<div class=”td-ss-main-sidebar”>
<?php dynamic_sidebar( ‘td-default’ ); ?>
</div>
</div>
</div> <!– /.td-pb-row –>
</div>
</div> <!– /.td-container –>

<?php
get_footer();

thanks Calin,
regarding the sidebar… how can I in the specific tag code call a custom sidebar?

I imagine is possible to change this call <?php dynamic_sidebar( ‘td-default’ ); ?>

the header is more complicated… I just need to have a custom ads banner in the tag page…
