Restoring defaults for hardware acceleration

Under the FAQ chart for WhateverGreen compatibility, there is a list of overrides for accelerated codecs:

defaults write com.apple.AppleGVA gvaForceAMDKE -boolean yes defaults write com.apple.AppleGVA gvaForceAMDAVCDecode -boolean yes defaults write com.apple.AppleGVA gvaForceAMDAVCEncode -boolean yes defaults write com.apple.AppleGVA gvaForceAMDHEVCDecode -boolean yes defaults write com.apple.AppleGVA disableGVAEncryption -string YES defaults write com.apple.coremedia hardwareVideoDecoder -string force defaults write com.apple.coremedia hardwareVideoDecoder -string disable 

How would I go about correctly disabling/reverting these overrides? Final Cut Pro and Compressor do not perform correctly anymore after applying a few of them, as my system has crashed a couple times during rendering due to this.
