No. In warfare you either destroy an exposed force or you give it the opportunity to somehow withdraw or counterattack. The Ukrainians were not able to destroy a Russian convoy that stretched for nine miles and sat motionless for two weeks earlier in the war. The tactical opportunity at Kherson rarely occurs in war. Competent commanders would take advantage of such an opportunity.

Google “siege” for more options. Also “cordon”.
Actually the did destroy most of the convoy - you just were not shown images of it or missed them them they were.
There is no point in wasting resources taking cut off Russian troops - this is not your Insurgency ... this is a different sort of war.
They will surrender when their stomachs start to growl or when they start to freeze in the winter.
