Built-in VR support clipping planes hiding my terrain!!

Hi!

I am having some trouble with the built-in support for VR applications in Unity. I am currently working with Vuforia as my VR SDK (defined in Edit > Project Settings > Player > XR settings). In Vuforia i defined its configuration (VuforiaConfiguration) to Digital Eye wear = Phone + Viewer (with the type preset of a generic cardboard).

When i play the scene four VR clipping planes are added to the hierarchy and as a result they end up hiding parts of my terrain in the game area. I've since then tried to adjust the "ARCamera" object culling mask settings, and also the near and far clipping planes, without any success.

Is there any way to setup these clipping planes differently, for example, to change what they hide?

Here's an image with what i mean: Only part of the terrain is visible, yet all the other objects in the scene are visible.
