Hello.
Almost all hosting providers include PHP Phar and PHP Zlib (PHP Zip) extensions as standard because they are essential for many applications. If your current hosting provider cannot enable these extensions, it might be worth considering switching to a hosting provider that supports them and with batter disk space to not worry about cache folder.

Alternatively, if switching hosting is not an option for now, you still have the possibility of upgrading manually. While it may require more effort, it can be a temporary workaround until you find a better hosting solution.
