Windows 10 won't boot in UEFI on Samsung Evo 970 NVMe

Recently I finished my build with a Samsung Evo 970 1TB Nvme drive. I originally tried to install Windows 7 on it but that failed. I went ahead and gave in on installing Win10 on it. I cleaned it and converted it to GPT in disk part. Booted from USB with Win10 in UEFI and installed it on the nvme. When it finishes and I go into BIOS, it does not allow me to boot in UEFI on that drive. Only legacy which does not work. I've tried reinstalling it, enabling Win10 whql support and disabling it, nothing works.

I plugged my install USB into the 2.0 slot for shits and giggles and it worked. Not entirely sure if this was the fix, but it worked.
