PS4 doesn't need DirectX. Detroit Become Human on PC runs on Vulkan, so does RDR2.

Yeah  i mean PS4 are build based X86. It's compatible either with Vulcan, Linux, or directX or every X86 program and engine. 

Developers do need to build their games to target specific API's and their instructions/features.

If a developer is lazy though, they will just write their own API wrapper, in the old days a developer would build their game on OpenGL and use a wrapper to interface with 3dfx Glide or Direct X, the game is still OpenGL based though, not something that happens much in the modern era of course.
