Thank you for taking the time to report this bug and helping to make Ubuntu better.
mesa-vulkan-drivers was added as a recommends for Debian packaging as of version 1.0.0.56-2 and therefore to the Ubuntu packaging as of version 1:1.0.0.61-2ubuntu1 (Ubuntu 20.04).
For Nvidia the Ubuntu package suggests the libnvidia-gl-NNN package which I believe includes the required vulkan parts.
Therefore I am going to mark this bug as fixed released. Please open a new bug if this does not work for you.
