Flaky Vulkan support?

[6SixTy]

Title. I've basically pinpointed down the issue to my iGPU drivers rolling back to some archaic driver version after my laptop goes to sleep or the lid is closed, taking away Vulkan support for both GPUs somehow. Newest OEM driver version doesn't enable Vulkan but AMD's drivers do, and installed one after another it rolled back to the same archaic driver version. Installing AMD drivers also enables Vulkan for both GPUs, which is also odd to me.

 

Is there any fix or am I SOL?

 

UPDATE: I rolled back my iGPU drivers from device manager, and it brought back the AMD drivers and Vulkan support for both GPUs. Is there something I can tweak to stop this behavior?
