Explanation

DX11 mode doesn't work; game always runs DX12 regardless of settings
Game: Deep Rock Galactic: Rogue Core Build: RC: EA:00.07.09 (Build 143055) Platform: Steam (2605790)
What's happening
The game runs DX12 no matter what. I've tried every way I can find to force DX11 to no avail.
What I tried
In RogueCore/Saved/Config/Windows/GameUserSettings.ini:

[D3DRHIPreference]

PreferredRHI=dx11

bUseD3D12InGame=False

Also set EnableDx12ByDefault=False under [/Script/RogueCore.FSDGameUserSettings].

There's also a "Use DX12" toggle in the in-game graphics settings, but it doesn’t seem to do anything. I also tried adding -dx11 in Steam launch options.

The only pipeline cache the game ever creates is RogueCore_PCD3D_SM6.upipelinecache (SM6 = DX12). There's never an SM5 file no matter what combination of settings I use.
Why it matters
DX11 translation on Linux and macOS is way more mature than DX12 translation. DXVK and DXMT handle DX11 well, but DX12 through translation layers (D3DMetal, vkd3d-proton) is rougher and causes performance issues that DX11 wouldn't have. The original DRG supports DX11 fine, and the config structure for it clearly exists in Rogue Core — it just doesn't do anything.

This would also help anyone on older hardware that supports DX11 but not DX12 well.
Repro steps
Set the ini values above
Add -dx11 to launch options
Launch the game
Check RogueCore/Saved/ to see that only RogueCore_PCD3D_SM6.upipelinecache exists, no SM5
System
Running on macOS (m4 max, Tahoe 26.2 via CrossOver) but this would affect anywhere wanting to run DX11
