You can use Zink (https://docs.mesa3d.org/drivers/zink.html) to translate OpenGL to Vulkan.

I have even used it in Windows to make a legacy proprietary OpenGL application work properly with recent Windows versions + a mobile (now unsupported) AMD GPU.

I use Zink for some games that rely on OpenGL since it works better with Mangohud as a Vulkan layer. For example all games that need scummvm or dosbox.
