Can I restrict the cloud storage options on my Creative Cloud and Acrobat installs to just one drive?
You mean you wish to disable the file saving option for Creative Cloud and Acrobat's Document Cloud storage. And wants to keep saving the file on Google Drive instead?
Other than Adobe's Cloud storage, you have these options for file saving well:
Making the following changes Acrobat>Edit.Preferences>General>uncheck "Show online storage when saving files " in the Acrobat preferences setting, which will only help you to stop saving the files to all the Cloud storage. But if you wish to disable only CC and Document Cloud storage, that would not be possible.
