If you use gparted to disable your existing EFI partition prior to install, and if you have followed the advice to create a gpt partition table and an EFI partition, you can work around it.
After the install, use gparted to reflag your internal EFI partition.
This worked for me with Ubuntu 18.04 on a new Thinkpad t480 dual boot, with a new install to a thumb drive.
