How can I prevent the death of this major NPC at the end of the Battle of Kaer Morhen?

How can I prevent

Vesemir

from dying at the end of 'The Battle of Kaer Morhen'?

What kind of choices do I have to make in the preparation of this battle to let this person survive?


No. His death is a major narrative event that needs to happen for the story. Sorry for your loss.
