Can I enlarge the EFI Partition? And if so how?
I used Rod Smith answer and comments @ https://superuser.com/questions/1142967/can-i-enlarge-mac-efi-partition-and-if-so-how and understood that the EFI partition does not have to be the first partition on the drive.
So basically I performed the following procedure:


Marked the EFI partition as normal data partition
Created another 500MB partition, marked it as EFI
Installed the OS and moved the boot.wim to the new EFI and let the deployment procedure complete
After the deployment completed I marked the old partition back to EFI and deleted the new partition I created, and voila! the OS deployed successfully and the drive returned to its original state
