Vulkan not available as VulkanRHI not present.

I try to package an android vulkan project.
But it fallbacks to OpenGLES.
The log shows that “|AndroidPlatformMisc.cpp:2269|Vulkan not available as VulkanRHI not present.”

Then I check the source code. Find that FModuleManager::Get().ModuleExists(TEXT(“VulkanRHI”) return false.

so how to make the Engine find VulkanRHI Module
