Unnecessary queries on every ajax call

Noticed that on every /wp-admin/admin-ajax.php request there is SQL query such as:
SELECT autoload FROM wp_options WHERE option_name = '_transient_xmlsf_flush_rewrite_rules'

This is responsible function:

public function transients_actions()
	{
		// CATCH TRANSIENT for flushing rewrite rules after the sitemaps setting has changed
		delete_transient('xmlsf_flush_rewrite_rules') && flush_rewrite_rules();

		// CATCH TRANSIENT for static file check
		delete_transient('xmlsf_check_static_files') && $this->check_static_files();
	}

Is it possible to change this logic, to avoid deleting transient on every ajax request?
