I need assistance deploying Windows 10 a Latitude 5480 via SCCM

Hello all, i'm running into trouble with my task sequence to build an image for the 5480. I'm able to PXE boot in legacy mode but whenever i use a BIOS to UEFI task sequence it fails whenever trying to switch over to PXE via UEFI. I'm currently stuck with this so any help would be welcome.
