By default we don't have the Imagick PHP library enabled on our servers.
This boils down to rather excessive memory leaks within the module in general which causes more problems than what's acceptable.
WordPress SiteHealth may complain that Imagick is not available, however, it's worth noting that Imagick is only required for generating PDF previews, something that's fairly uncommon.
If you're using WordPress then you can use the ImageMagick Engine plugin and set it to "ImageMagick Command-line".
