D3D11 Create Device

I was wondering how to create/use a direct3d device in unreal engine 4. I was thinking I could just call the function D3D11createdevice from the d3d11 library, or is there something in the frhi renderer that you can use. Also, because I noticed in the standalonerenderer folder underneath developer looks so similar to the direct3d functions I’m familiar with, can you just take those functions, and if you could, what #include would you use?

I apologize if my questions come off as very amateur, but I am quite the novice. Any help would be much appreciated, than you.
