No in my experience

terminal

sudo -s
type password
diskutil list

find efi disk #

ewfs_msdos -v EFI /dev/diskXsX

for example disk0s3 or disk1s3

I reformatted my drive to another scheme - exFAT or APM or something. Then reformatted back to GUID to wipe out the EFI partition (and every other partition) quickly.

How to access the terminal from Clover to enter this command to format the drive? I like to do a clean install. Thank you!

if I mount the efi partition can I use finder to delete everything in it?
