Can we get main branch in original state ( before publishing any changes on VB ) provided by Oracle

Summary:

Can we get main branch in original state ( before publishing any changes on VB ) provided by Oracle?

Content (please ensure you mask any confidential information):

During testing and POCs on VB, developers and other testes have committed changes in main branch in a project. But those are not actual changes instead just testing.

Can we start from scratch and get main branch in the same state that oracle provided , so we can start the actual work?
Is there any way ?
