Any idea to accelerate UV unwrapping process?

[gganjang]

I ran mvdream to do text-to-3D object thing, and the result looked good after iterations. Since I needed .obj file from the model, I ran export command with 512_tet.npz which gave me much better result than 128_tets.npz.
My problem here is that the process of UV unwrapping (as the log says..) took over 24 hours, and I think this is not the best usecase for sure.
Is there anything I can do to make better quality result with the shorter amount of time???

Below is my command for exporting:
python launch.py --config "${CONFIG_FILE}" --export --gpu 0 resume="${CHECKPOINT_FILE}" system.exporter_type=mesh-exporter system.exporter.context_type=cuda system.geometry.isosurface_resolution=512 system.ge ometry.isosurface_threshold=15.

And the result
