Would vulkan1.2 be able for this project?

I want to deploy 3D Gaussian Splatting (3DGS) on edge devices, but some of these devices only support Vulkan up to version 1.2. Currently, all Vulkan-related implementations in existing 3DGS projects use version 1.3 or higher. Is it feasible to downgrade the Vulkan requirement to 1.2?
