I don't like the distracting health, stamina, and magicka bars, or the stealth meter, and I especially dislike the arrow count display.  They're all very distracting and there're unfortunately no ini settings to get rid of them without bombing the HUD entirely, so I messed with the vr_hmd_info.swf file and set them all to scale to 0, so they dissapear. 

There is probably a better way to do it, and if you know it, then feel free to explain how much I suck and how great your method is in the comments; I've never messed with swf files before, so the opportunity to learn is appreciated.

A brief description of how I did it, so you can customize it more: 
    1. I extracted the interface\vr\vr_hmd_info.swf file from the Skyrim_VR - Main.bsa file 
    2. I opened it in JPEXS Free Flash Decompiler (easy to use, but I'm sure there are better tools for this), 
          - click No to all for the prompt
    3. I expanded DefineSprite (1236: HUDMovie) object, 
    4. I went to HUD parts I didn't like (StealthMeterInstance, Health, Magica, Stamina, and ArrowInfoInstance)
    5. For each of them: I clicked the edit button on the info window
          - expanded the matrix object
          - set the hasScale field to true
          - set the scaleX and scaleY fields to 0
    6. Then save and put the file in the data\interface\vr folder
