centos7 - How do I change the default PHP base-version on shell?

Question

I have Centos 7 and Virtualmin installed, with the tipycal php-fpm 5.4, 7.0, 7.1 that you can choice between the versions you prefer on every virtualhost via Virtualmin control panel, and everything works well.

But when I access to the server via SSH and check php -v I get this:

PHP 5.4.16 (cli) (built: Oct 30 2018 19:30:51) Copyright (c) 1997-2013 The PHP Group Zend Engine v2.4.0, Copyright (c) 1998-2013 Zend Technologies

How can I select another php default/base version for the shell system?
