Setting focal point / Fighting close-up blur

Is there some way to set focal point of the OVR cameras in Unity?

I noticed that when I get very close to an object, about 10 cm or less, they start to blur. But if I focus my eyes on the background while remaining close to the object, the object becomes sharper (even though it "splits" in two). If I understand correctly, this is because the focal point of the Unity cameras (where their line of sight converge) is far away, prioritizing distance focus over close-up focus.

I want to experiment with other focal points to see if they're better suited for my demo, or maybe even make a script that adjusts it depending on if a nearby object covers a large enough portion of your screen. Is this possible?

Or did I completely misunderstand this? :)
