Unless this can be reproduced with upstream vkd3d and without third-party DLLs and workarounds, please take this discussion to another channel.
There is no DX12 renderer in the Warframe launcher options with upstream vkd3d as well (tried 1.2 and latest git version), but it's missing even with older Wine versions, even though other DX12 applications seem to work fine (tested UE4 Elemental Demo in DX12 mode and it works).
I also tested wine @3b63afeeba29a76e19eee41a90c9a32838645cf9 aswell as wine-staging-6.5 and wine-staging-6.7 with upstream vkd3d @8b99fc66d3b4dba3d213c7115aa79a22ece38719
No D3D12 option available in any of them. So in a sense, vkd3d does not work AT ALL vs. vkd3d-proton works with <= 3b63afeeba29a76e19eee41a90c9a32838645cf9.
So it could be said that fixing D3D12 support for Warframe with upstream vkd3d would be nice :) (But then better suited for a new bug-report)
