This solution didn’t work for me. I made the post author id 1 or the admin and got the same result AFTER spending a LONG time trying to make my “guest author” have the right capabilities without success. I am using CPT UI to make my taxonomies and post types. For not logged in users save_post was my solution…

Make your own inputs with whatever values you want:

$htmlAfter = '<input type="hidden" name="tax_name" id="tax_name" value="ENTER_MAIN_TAXONOMY_SLUG">';
$htmlAfter .= '<input type="hidden" name="tax_slug" id="tax_slug" value="ENTER_INDIVIDUAL_TAXONOMY_SLUG">';

Add those inputs to acf_form function with html_after_fields parameter (or html_before_fields):

'html_after_fields' => $htmlAfter

Save those values ($_POST) as you wish with save_post action:

function my_acf_save_post( $post_id ) {
    
   if(isset($_POST['tax_name']) && isset($_POST['tax_slug'])) {
	 wp_set_object_terms( $post_id, $_POST['tax_slug'], $_POST['tax_name'], true );
	}
    
}

// run after ACF saves the $_POST['acf'] data
add_action('acf/save_post', 'my_acf_save_post', 20);
