The Switch went through Vulkan 1.0 conformance testing, and then again for Vulkan 1.1 and 1.2 https://www.khronos.org/conformance/adopters/conformant-products#submission_521 https://www.khronos.org/conformance/adopters/conformant-prod... There's also a platform integration extension attributed to NVIDIA and Nintendo https://www.khronos.org/registry/vulkan/specs/1.2-extensions/man/html/VK_NN_vi_surface.html https://www.khronos.org/registry/vulkan/specs/1.2-extensions... Seems unlikely they would go to that trouble if Vulkan weren't actually exposed to developers
