[SOLVED] Development indications at the source code bottom

I wanted to remove the development indications on my production LC e-shop that appear at the bottom of the source code. Is it possible?

They are found in app_footer.inc.php and will in the next major be shown only to admins.

Does that mean this data cannot be deactivated?

file: includes/app_footer.inc.php
Comment out this line:

echo PHP_EOL . stats::render();

Thank you very much jackmaessen for the correction note which I have adjusted immediately!
