Hi,
As far as I know there is no list of what drivers are updated via Windows Update, the closest I could think of is to look for the keyword "driver" in the Microsoft Update Catalog:
https://www.catalog.update.microsoft.com/Search.aspx?q=driver
This should list you most drivers available via Windows Update.
(If the reply was helpful please don't forget to accept as answer, thank you)
Best regards,
Leon
