No. Russians are trying to stop the counter offensive. This move will free up troops to defend Melitopol. Capturing that city effectively blocks land supply route to Crimea.
That is if Ukrainian forces were concentrated elsewhere based on a plan to burst the dam.
If they win on other fronts they can turn attention south by that time Crimea will have not had fresh water for months and the forces will be depleted and demoralised.
This could be a major factor in the new offensive. But will require careful planning (if that didn't happen already).
To be honest, I see the resolution more to do with securing better grain deal security.
