When disabling cloud storage via registry or GPO it breaks Fill & Sign

Hi, this is a beaten subject, multiples hits on the requirement to disable Adobe Cloud and yet zero support from Adobe, just spent 3 hours on a phone with Adobe support oh my oh my.

Thank you for multiple posters on this board - this is how I found feature lockdown information via windows registry, the keys bToggleDocumentCloud and bToggleSendAndTrack

This accomplishes exactly what I want - it removes the cloud icon from the interface and does not allow users to save file to Adobe cloud - perfect! But it breaks "Fill and Sign” because Acrobat stores signatures in cloud - now when cloud integration is blocked I can not create/use signature to sign a document. 

How can I configure Acrobat to store signature locally? I can use a key bToggleFSSSignatureSaving to stop Acrobat from saving signature - but this creates a problem for the user, every time user wants to sign a document a new signature needs to be created. 

Is there a registry key that will force Acrobat to keep all files (config/signature/etc) locally?

I'm deploying multiple workstation with Acrobat installed - looking to centralized solution using GPO or registry settings.

Thank you!
