No—Canon’s Dust Delete Data is proprietary and, based on the community answers, Lightroom, Adobe Camera Raw/Photoshop, Aperture, and Capture One do not use it. In practice, it’s meant for Canon’s own Digital Photo Professional.

If you want to stay in Lightroom, the practical workaround is manual cleanup with the Spot Removal/Healing tool on the images where the dust is visible. That’s often the simplest approach if the spots only appear in certain photos, such as skies or HDR images with bright, even tones.

If dust is showing up frequently and a blower isn’t helping, the particles may be stuck to the sensor filter, in which case a proper sensor cleaning may be needed.
