Can you drill a hole in carbon fiber handlebars?

Never, ever drill or damage the structure of carbon fibers in any way. It’s akin to cutting a woven rope with a knife, you’ll weaken it’s strength tremendously and that’s definetely not what you want in such a stress loaded device as a handlebar even if it seems overbuild.

How do you cut carbon tube?

When cutting composites, it is ideal to use a diamond coated abrasive cut-off blade rather than a toothed blade. Teeth can catch the fibers and tear the material resulting in splintering or delamination. Thicker tubes may generate enough heat to re-activate the epoxy causing the blade to “gum-up”.
