Yes and no. DXVK didn't happen on top of opengl as the impendence mismatch between OpenGL and DX is too large. Wine had working but slow DX9 to OGL; incomplete, buggy and slow DX11 to OGL; and no hope for DX12 to OGL. DX9, DX11 and DX12 are all much easier (but not easy, mind) to map to Vulkan.
As Steam Deck is running AMD, a conversion layer on top of Mesa Gallium would have been possible, but again DX12 support never materialized.
