Let me play Steam VR Games without the performance hungry device known as Oculus app running in the background.
Don't know about you... but whenever I play any steam vr game (which I do much more often than oculus), it takes up about 26% of my cpu, and a decent chunk of my memory. All I really want is a way to play GORN without my cpu ******** itself, due to the oculus app. Make it less performance hungry, or just an option to make it gone in general.
This is not possible. Oculus app has to convert sensors output to 3D position values. It is the same as Vive Cosmos: It also needs its external app for converting sensor output to 3D position values, that can be then used in Steam VR. Only devices that use Steam VR tracking (lighthouses) don't need to use any external apps, because Steam VR does this conversion from sensor to 3D position.
Try to set Oculus to run as administrator, so it won't open unless you allow it to.
It does not affect your Pc when you are playing a game.

Even with Oculus Tray Tool, it still tends to sync a good 20% of my idle CPU

I don't mean to sound elitist here, but uh... you could just upgrade your rig? I have decent specs, not fantastic, but I can still play everything with both open just fine, so it might be more about your specific setup than the software itself.
Try with openComposite
I played Elite Dangerous (Steam version) with the steamvr not active. Runs nice, if i activate it, i got frame drops. Both runing with the oculus app on desktop. Did you try not actvating steamvr?
