CyberPanel only install LiteSpeed PHPs from LiteSpeed repos. Installation directory for PHP is located at
/usr/local/lsws/lsphpXX
You need to replace XX in the path above with PHP version, for example the path for PHP version 7.4 is /usr/local/lsws/lsphp74
And PHP CLI binary path for each PHP version is
/usr/local/lsws/lsphpXX/bin/php

During installation CyberPanel installation code runs following command to set Global PHP CLI:

Which means by default the Global PHP for CLI is 7.4, upon running php -v on command line you will get:
root@ip-172-31-34-208:~# php -v
PHP 7.4.16 (cli) (built: Mar 4 2021 16:36:45) ( NTS )

ln -s /usr/bin/php /usr/local/lsws/lsphp80/bin/php
Set Command line to PHP 7.3
ln -s /usr/bin/php /usr/local/lsws/lsphp73/bin/php
Set Command line to PHP 7.2

How to use specific PHP Version in your Cron Jobs?
Some applications requires you to set cron jobs and they require PHP CLI executable. Now rather then changing default global php binary version, you can use direct path to that CLI.
For example an application requires that its script should be running through PHP 7.2, you can use the direct path for its binary rather then updating a global binary, such as
/usr/local/lsws/lsphp71/bin/php <your command goes here>
