Dependency conflict (library dataclasses with python >= 3.7)

[VGODIE]

I use python==3.8 and dvc == 2.9.3 in my project, however the addition of lightautoml package has broken the workflow with dvc. The following error occured:
AttributeError: module 'typing' has no attribute '_ClassVar'
I have searched what might be the cause and have found some close issues:

• [Serve] Only install dataclasses on Python 3.6 ray-project/ray#10936
• Tune example on landing page is broken! ray-project/ray#12091

So, it is said that the problem is in library dataclasses which is inconsistent with python >= 3.7. And the suggested solution to it is to add conditional dependency: to only include dataclasses as a dependency if the python version is less than 3.7.

So my issue is about asking if it is possible to make such dependency change to let use later versions of python, dvc and lightautoml together ?
