DLSS-G / Vulkan application

I am interested in using DLSS-G within a Vulkan application. I’m a little unclear on its availability/support in Vulkan. On the Streamline Get Started Page, the engine requirements field states Directx 12, but when I go to ProgrammingGuideDLSS_G.md on Github it appears that Vulkan is supported.

I plan to use DLSS-G in a plugin being built for a host application where I will likely need support from the host application development team. I would like to make sure this is a viable feature to integrate into my plugin before I start making any RFEs.
