How to force the engine to run at a lower feature set?

Development Rendering
1

I’ve packaged my game and am running it in VMWare to try and test some networking capabilities. Don’t know how well that’s going to work, but I’ve already run into an issue.
VMWare supports DirectX11, but not the entire feature set it seems. I tried passing -d3d10 and -opengl command line parameters (in target), but the former doesn’t seem to do
anything and the latter throws a similar error - ‘OpenGL 3.2 is not supported’.

Is there something else I can try?

Thank you.

Edit:

I noticed Project Settings -> Platforms -> Windows -> Target RHIs. I unchecked DX11 and only kept DX10, but when I package my game I get an uncached global shader error or some such.
