Purpose of this PR

This PR was causing Yamato-only failures that disappeared once batch mode was disabled: #1053

The ideal fix would be to resolve why this is only happening in batch mode and fix that, but due to limited SDET resources, it's better to simply disable batchmode for this project for now. This slows down testing, but eliminates failures that only appear in batchmode.
