Using two or more graphics cards at the same time

Currently, the original Stable Diffusion can only use a single graphics card.

But with DirectML we can in theory combine several graphics cards into 1 and use them all to speed up computation.

that is, due to the lack of support in DirectML there will not be yet?

torch-directml does not support any data parallelism techniques and even it can't move tensors directly between gpus.
