Can VIVE OpenXR Windows Unity Plugin Work with OpenGL on VIVE XR Elite?

[MrKill]

I am now using Unity 2023.3.21 to develop software for VIVE XR Elite. Since I need to use PC VR mode, I choose to use the VIVE OpenXR Plugin - Windows. I found that it can perfectly work with DX11 graphics API. But once I switch to OpenGL graphics API, I cannot see anything from my XR Elite. Does that mean the plugin cannot support OpenGL? I really need it works with OpenGL because an important plugin needs it.

If it cannot, how can I use some OpenGL-required plugin under PC VR mode? Any suggestions?
