This is something of a feature request/feedback.
It would be useful when selecting multiple different variants with the same style options if we could bulk change them.
ie. An icon set with a separate component for each icon, each with an outlined, filled, two-toned style. When selecting multiple icons wit the same style set, they could all be changed from outlined → filled. Currently, because each component would have a different name (that of the icon) Figma doesn’t allow for bulk editing of the variant style.
