Big Sur 11.6 - GA-Z97-D3H - Samsung T5 SSD not powering up with boot

Successfully installed Big Sur 11.6 using opencore guide.
USB Mapping also done using opencore guide.
USB 2.0 and USB 3.0 drives working but Samsung T5 ext ssd not powering up at boot.
But it works if I unplug it and plug it back in once i have reached the desktop after boot.
Would appreciate if anyone can have a look at my EFI and figure it out.

System Specs :
GA-Z97-D3H
i7 4790
RX 580
