…
You’re looking for DoScreenSpaceReflections in ScreenSpaceReflections.cpp. If VXGI specular is enabled, then it just returns false. it would be better if you could enable both without changing the source code, but the VXGI branch defaults should probably change SSR to default to disabled.

If you enable VXGI+SSR, you probably also want to change ReflectionEnvironmentShaders.usf so it blends SSR with the VXGI specular.
// NVCHANGE_BEGIN: Add VXGI
#if APPLY_VXGI
	SpecularLighting.rgb = ScreenSpaceData.VxgiSpecular.rgb;
#endif
// NVCHANGE_END: Add VXGI

#if APPLY_SSR
	float4 SSR = Texture2DSample( ScreenSpaceReflectionsTexture, ScreenSpaceReflectionsSampler, UV );
	SpecularLighting.rgb = SpecularLighting.rgb * (1 - SSR.a) + SSR.rgb;
#endif

Great, thank you very much.
