How can I install a UEFI firmware update blocked by system?

System Acer R5-471T, Windows 10 Home 10.0.17134

After the April 2018 Windows 10 update, the system is notifying a device driver problem for "Acer Inc. System Firmware 1.12", specifically:
"This device cannot start. (Code 10)

"{Access Denied}
A process has requested access to an object, but has not been granted those access rights."

Event logs suggest this device driver update was done at around the same time as the major Windows update, though the firmware files date from November 2017.
When I tried to re-install, I got Code 14s (restart required to complete) after successive restarts.  A roll-back installs a Microsoft generic driver. 

Is there a way to fix this?  What problems will I have if I just disable the driver?
I notice there's a recent version (1.13) on the support site, probably too recent to have reached the Windows Update Catalog.  Is this likely to face the same problem on a future update?
