EFI on Fusion Drive ?

Hi, i currently have a late 2013 iMac 27" with a fusion drive and i was wondering where to flash the efi on the disk because OC does not support the fusion drive and I don't want to split it. It gives me the choice between the 1.0 To HDD and the 112 Go SSD I currently have a Sequoia partition on an old external 5400RPM laptop hard drive
