If you are using the latest Windows 11 ISO, then really the only updates that should need to be installed after that are the two October updates and possibly a security update for Windows Defender.
There is no method available to copy those updates out of the PC already fully updated, then best option when using the ISO to upgrade the systems is at the start of the process, choose the option not to install other updates.
Then when that completes, you can if you wish, download the offline installers for the October updates (KB5066835 and KB5070773) directly from the Microsoft Catalog (https://www.catalog.update.microsoft.com/Home.aspx), but only install those on a system that has been updated to 25H2.
