Questions about finite deformation NEB,

I saw in a paper that finite deformation NEB was performed using Lammps. It seems to have utilized VSMP, but it is not in the manual, so I have a question. I want to know specifically how to do DFT-NEB calculations for the process in which the lattice changes. In particular, most NEBs in which the lattice changes have a stress-strain relationship, but I want to perform NEBs in which the structure changes through heat. Is there any way to do this?
