System image creation (on windows 10) fails because EFI system partition is locked.

Windows 7 system image creation (on windows 10) fails because EFI system partition is locked. There is no error code. Microsoft support hints that the lock may be held by the anti-virus program. 
System is HP Envy Curved-all-in-one PC 34-b0xx.
OS is Windows 10 Home V 1709 Build 16299.431.  
Trend Maximum Security V12.0
I use windows 7 backup to save files on an external HDD.

How can the lock be released so I can successfully backup my data?

If not possible, I need an alternative backup and restore solution. Any suggestions.

I have not had a successful backup for several months. Please treat this as a high priority.
