Displacement map UV

[fprpic]

As vray displacement only works with map applied to the group/component, not face, how to control in sketchup the UV mapping for that texture? See the example here https://i.imgur.com/Ffk64Xp.jpg
I would like to move the texture on one of the sides so I can align textures more precisely

The position and transformations of a texture applied on a face will affect the displacement mapping. It just needs to have the material with displacement applied on group/component level as well. In your case, you can easily fix the misalignment using the V-Ray UV tools from the toolbar or the context menu:
