Cannot see oclp efi when I boot into startup manager- iMac 13,1

I am attempting to update my iMac from Catalina to the new Sequoia, however, when I hold the option key there is not option to select the EFI only the main drive. I have followed all the steps and I have made sure the USB is bootable so there is no issue on that end. I have installed the OS on the USB and OCLP and it has successfully installed the efi. I have tried to reset the VRAM and nothing has helped. Any ideas?
