Certainly not that I know of, and as I mentioned in my other comment, it seems so obviously counterproductive, I would look at it with an extremely skeptical eye if someone from the Kremlin did say something weird as hell like that.

No, as usual, it's just western projection and lies. Because Russia did attack places in western Ukraine early on, NAFO types take that as undeniable proof that Russia wanted to take all of Ukraine and thought it could do so in a week but failed (like that weeks Saturday morning cartoon villain, Putin shaking his fist but promising he'll be back next week). So it becomes part of the canonical text of The Narrative. It also allows NATO/the west/US to claim they didn't actually lose the war because "Look! See, Russia didn't take over all of Ukraine like we know they wanted to! We won afterall!" When Ukraine's military finally collapses, and Russia's terms don't include making the entirety Ukraine part of Russia proper, that's what everyone in the west will be using as their strongest copium.
