Not currently, but it is needed and has been requested. We certainly need a global way to determine what render path AGKS selects in addition to being able to set it ourselves. A 'software' type render mode has also been requested for those of us interested in writing server apps that don't require 3D hardware/drivers and only need to display text. My request was long these lines:
SetRenderMode(#) where # would be 0 = software, 1 = OpenGL, 2 = Vulkan
return=GetRenderMode() where the return would be the same, 0 = software, 1 = OpenGL, 2 = Vulkan
