Render only textures within (0,0) to (1,1) texture coordinate range?

I have added a texture coordinate array to a .vtu object to define the texture coordinates:

However, I cannot figure out how to prevent the texture from rendering outside of the (0,0) to (1,1) texture range. I have to assign something to all the points in the array, and assigning anything <=0 or >=1 just results in the texture being stretched out into the remaining space.

Is there a way to avoid this in ParaView with XML .vtu files? I could possibly edit my image to include a transparent border, but I don’t want to add an unnecessary and pre-processing step if possible.
