Your GPU is a GT 540M rebrand , a Fermi GPU . So it doesn't support Dx12 and Vulkan

Intel HD 4600 does support DX12 and Vulkan however you won't notice any performance gain due to the lack of feature level
The bare minimum requirement for DX12 and Vulkan is Kepler .
Nvidia architecture : Tesla < Fermi < Kepler < Maxwell < Pascal
