As of this moment, DAVE is available on conda-forge and a python 3.8 version of pyo3d has been added.
Installation of dave can now be done using:
conda install -c conda-forge dave
However, installation of mafredo and vtkplotter are still via pip. And installation of pyo3d is still via a manual download link.
Full installation instructions have been updated accordingly and can be found under DAVE->Installation
