At In GitLab one of the developers (Faith Ekstrand) revealed that NVK now supports the Vulkan 1.3 specification. The development of support for the VK_KHR_shader_float16_int8 (vk 1.2) and VK_EXT_texture_compression_astc_hdr (vk 1.3) extensions took a considerable amount of time.
Now Vulkan 1.3 support is available, but there remains much to implement in terms of extensions. (nvk Extensions:126(56.0%), Version 1.3).
