Can I make a VR game without Steam VR?

Hello.
I am currently creating a PC based VR game.
It is intended to be played with Oculus Quest2 connected to a PC.

When packaged and played, Steam VR will be activated together.
How can I create a PC based VR game in some other way without using Steam VR?

UE 4.27.2 or 5.1
Windows 10
Oculus Quest 2

Hey there @vs_studio! You can develop directly for OpenXR, however SteamVR is middleman for when you’re working on the project.
