Start the work while waiting for GPU Updates

Hi, I am going to start a project with my team and we are going to use the UE4.

The PCs we will work on are ok if not higher than the minimum requirements stated for the engine, but We Have to update some of the GPUs.

I was wandering if it could be possible to start the work with a Directx10 Graphic Card, since we are not planning about using directx11 features at the moment. I don’t want to pay the engine and not being able to use it.

Anyone had this kind of experience? If anyone did it or is doing it, I’d like to know if I can start with UE4 while we wait for the new Craphic Cards.

Thanks Everyone!

P.s.
Please no suppositions, I need to be sure.
