For those who may not be aware, these Dynamic Update packages are meant to be applied to existing Windows images prior to their deployment. In a Tech Community blog post about Windows 10 Dynamic Updates, Microsoft explained Dynamic Updates in more detail regarding its various components and uses. These packages include fixes to Setup.exe binaries, SafeOS updates for Windows Recovery Environment, and more:

As soon as a Windows 10 feature update initiates, whether from media or a Windows Update service-connected environment, Dynamic Update is one of the first steps invoked. Windows 10 Setup reaches out to an Internet-facing URL hosted by Microsoft to fetch Dynamic Update content, then applies those updates to your OS installation media.

 

Content acquired includes:

 

• Setup Updates: Fixes to Setup binaries or any files that Setup uses for feature updates.
• Safe OS Updates: Fixes for the "safe OS" that are used to update Windows recovery environment (WinRE).

 

In addition to these updates, Dynamic Update will preserve Language Pack (LP) and Features on Demand (FODs) content during the upgrade process. These are not updates to LPs and FODs, but reacquisition to ensure the user has these elements present with the update completes.

The Setup updates are available for manual downloading from the Windows Update Catalog website. You can find them here: KB5053424 / KB5053485. You can also avail of the WinRE updates manually there at KB5053426 / KB5052424.
