Disable futher voting if node is "expired"

Hello,
I don't know how to explain my issue but I'll try... I would like to ask how I can disable voting on certain nodes after certain time? I have a website where users can vote up or down, but I would like to have a option to disallow further voting when node is "expired" and display only number of votes. For example when I want to block further comments, I also would like to block further voting and show only number of current votes on this node

In content templates I have code like

<?= $node->content['vote_up_down']['#value'] ?>

Can I put something like

<?php if($node->content['comments_are_disabled']): ?><?php print $node->content['vote_up_down_show_only_results_and_disable_futher_voting']['#value']<?php endif; ?>

Please help
Thank you
