How to get Security update only for window 10 and server 2019?

So previously for Win7 and servers up to 2012R, we push out [Security Monthly Quality Roll up ] updates, looks like they are no longer available for Windows 10 and Server 2019?

What is the current Windows update module for Win10 and Server2019, I was searching these update package in Microsoft®Update Catalog and there is no results returned about Win10 and Server2019.

Have the update model changed already?
