RTX 2060, Vulkan not available in RPCS3

The same problem happened to me.

I got it working, here's the how-to:
1. Close RPCS3,
2. Disable the AMD GPU (Vega graphics) from the Device Manager -> Display adapters,
3. Enable it again,
4. Open RPCS3 (Vulkan should available now).

If I reboot the laptop, the problem goes back and I will have to do the workaround again.
Well, at least it's working for now.

I'd be grateful if anyone try this and confirm it's working on your laptop too.
