Tested this on my setup.
Relevant specs:
Windows 10 21H2 (latest updates installed)
RTX 3070 GPU, 516.59 drivers + 3D vision driver installed for DX9 compatibility (courtesy of 3dfixmanager)
Primary display: 4k 120hz, Gsync Off
3dv1 glasses, tricks with CRU + NVTimingsed to force my monitor to work w/ 3d vision
Overlay software present (Discord, Steam). Even with both injecting overlays into the game, this seemed to have no ill effect on the fixes, geo-11, or stability of the game.
Link to fix:

Version used as of time of posting: v1.33
Process followed:
*Installed game, ran it at least once to confirm it works on my system
*Installed fix from above link, copied contents of geo-11 v0.6.10 over it (taking care to not move d3dx.ini to preserve the game fix settings)
Changed the following settings:
d3dx.ini: force_stereo = 2
d3dxdm.ini: direct_mode = nvidia_directx9
convergence/separation: to taste for my display
*Launched game. It worked!
Looks perfect. Seems nicely compatible with nvidia_dx9 mode of the fix. The GUI for the 3d vision setting changes defaults to the 3dvision version, and the fix hotkeys worked.
