Hello,
You should be able to change the PHP version from the VPanel.
Go to More Account Settings from the sidebar, Then on PHP Settings, there is an option to Change PHP Version.
Create a new file from file manager with any name (check.php) and paste this code
<?php phpinfo(); ?>
Open the file in the browser, the PHP version will be stated there.
It might sometimes take some time for changes to take effect.
Regards!
