You don't see to get it -- Russia will the entire country or render it uninhabitable if there Ukraine doesn't surrender and agree to remain neutral.
Neutrality would be reasonable concession and a justifiable demand from Russia. Indeed, Zelensky offered it and Putin could have it today if he were to leave Ukraine.
Russia is exhausted. It is doubtful that it could carry on the war for another year. Putin is not going to get his maximalist goals. He will have to make concessions or Trump will arm Ukraine to the teeth. Trump is not Biden and will not be pushed around. That said, Ukraine will also have to make concessions. The final form of an agreement is yet to be seen but it is not going to be the unilateral surrender by Ukrainian that you are dreaming of.
