Cannot Uninstall Latest Quality Update (KB4556799)

Running Win 10 Home, Version 1909 on Acer Aspire A515-43

When I go to Settings>Update History>Select Update I can see and highlight the update but there is no uninstall
option!
So I start in advanced startup mode - I can select the Uninstall latest Quality update option and get the message
"Sorry, we ran into a problem and cannot uninstall the latest quality update" message

How can I uninstall the update (and more important, why can't I uninstall using routine methods)
TIA

How do you uninstall chipset drivers?

I'm installing a new mobo so I need to uninstall the intel 865g drivers to make way for the P35 drivers.

Can't find any uninstall options in add/remove programs and intel chipset inst listed in driver cleaner.

Any suggestions? *Confused
