To create a Vulkan Device Filtering asset:
Unity creates the Vulkan Device Filtering Asset in the Assets folder with the file extension .vulkandevicefilter.
Each asset displays three filter lists in the InspectorA Unity window that displays information about the currently selected GameObject, asset or project settings, allowing you to inspect and edit the values. More info
See in Glossary window: Allow Filter List, Deny Filter List, and Preferred Graphics Jobs Filter List. The Deny Filter List includes Android device specifications that Unity restricts by default from using the Vulkan API. If your application performs better with these device specifications, you can override those by removing from the list.
