Where to manage PHP-Modules with NGINX installation

SYSTEM INFORMATION
OS type and version Ubuntu Linux 20.04.5
Webmin version 2.013
Usermin version 1.861
Virtualmin version 7.5
Theme version 20.13
Package updates All installed packages are up to date

I wonder where to manage which php-modules are installed currently.

Is there a section in Webmin or Virtualmin to tick some checkboxes to do it, or do I need to install it via Linux Package-Manager?

Would there be any additional configuration needed for NGINX (I use NGINX-Server)
