Calibrate Height WITHOUT Oculus Client? (Unity 5.4.5)

Hello Community! 

I'm trying to find a way to calibrate the floor height in Unity without the client (So I can implement in-game calibration). However, no matter what I do, (Even getting the eyeHeight values from the OVRPlugin.cs) It always sticks with what is set from the Oculus Client. 

If anything (Especially from Oculus's Support) Is there a way to do this without the Oculus Client?
