if you disable those efi's in your config.plist, then they won't show up in your boot picker
I just ended up clearing them from the Tools folder and it solved the problem. Thanks feartech. I'll update if installation goes well
EDIT: Installation went well but kernel panicked less than 5 minutes after installation. Here's the log it spat out:
