UEFI BIOS Type in PowerEdge T20

Hello community.

I have a question about BIOS type in PowerEdge T20 Server.

I want to install a PCIe SSD and boot Windows from it, but I have info about that only UEFI BIOS can support this feature. The question is; What type of BIOS have the PowerEdge T20 server?.

The PCIe SSD that plan to use is a Kingston Hyper Predator 460 GB on the PCIe 16x 2.0 x4 expansion slot.

Additionally, can I connect a SSD 2.5" without optional card controller?.

Thanks.

Regards
