angle use dx11 support multi context gl draw call?

    Recenty,I'm studying angle and preparing to apply it to my projects.I find that dx11 backend in angle use only one ID3D11DeviceContext in one D3DDisplay, which all egl context share only one D3DDisplay on one device in angle code,so if I have multi thread,each one create a egl context (not share) and call gl draw calls in thread for loop, is angle support my usage, if angle support how does it support the isolation in contexts with one ID3D11DeviceContext?

  please tell me a clear answer, Thank you!

No, the d3d backend of ANGLE does not support multithreading.

Only the Vulkan backend is thread-safe.
