Update to de lastest version of IIS

HI! In the company I work for, we have many servers with several versions of Windows Server (from 2012 R2 to 2022) and some of them have the IIS role installed. 

I have to check if IIS is updated in every server, so I'd  like to know if you can help me whit the following: 

1. How can I Update IIS to te lastest version? I searched the web and looks like the only way to upgrade it is using WIndows Update, but in my organisation it is disabled by policy.
2. I was searching for information about the different versions of IIS in Microsoft learn and all I found was this: https://learn.microsoft.com/es-es/lifecycle/products/internet-information-services-iis. I understand that there are several versions of IIS 10, some of the available only for Windows server 2019 and others only for Win Server 2022. Where can I find that info? 

Thank you.
