How to install an old version of imagick or imagemagick?

Question

PHP

imagick does not work correctly on php. When executing any script associated with the imagick module, an empty small transparent square is displayed on the site, and the html part does not load at all (ie, the site title is not displayed, etc.).

On one of the forums I saw that they solved the problem by installing the old version. But there it is not indicated by reinstalling what exactly (imagick or imagemagick) and how.

PHP 7.2
