Option to not export textures?

I am building a custom app that uses Verge3D. I have lots of different scenes, and they all use the same textures, so I have centralized those textures and set a URL modifier like this:

v3d.DefaultLoadingManager.setURLModifier((url) => {
    if (/\.(png|jpe?g|webp|hdr)$/i.test(url)) {
          return <code>${contentBase}/shared/textures/${url.split('/').pop()}</code>
        }
    return url
})

Because of this, it would be nice if when exporting my gltf from Blender, I could not export the textures – I don’t need them. I just have to delete them every single time. Is this a feature that exists? Or can it be added?
