I think what you are looking for are eyepoint line 6 of camera.cfg
>eyepoint = 0,0,2.5 ; (feet) longitudinal, lateral, vertical distance from reference datum
maybe it requires some adjustment as I don’t have any VR I can’t really tweak those numbers
I tried to watch those initial camera stats and realise I may be wrong in first instance
watching stats available in debug mode
it could be the coordinate from first camera [CAMERADEFINITION.0] and not eyepoint that require some change
edit : [CAMERADEFINITION.37]
line 1645 ; InitialXyz = -0.337585,0.094898,-0.248452
another edit : my correction are referring to this post making me realise I was wrong on everything 
my apologize
