How can I downgrade or use PHP 7.2 without uninstalling PHP 7.4? Is it possible to use PHP 7.2 as default instead of the latest version?

Question

I am using linux Ubuntu 18.04 And I wanna revert back to the previous version of PHP.

I've seen tutorials that requires me to uninstall the latest version, now I am asking if there is a workaround in this problem such that I can easily switch from using 7.2 or 7.4.
