How do I disable the Adobe ID login popup

Hi,

Im installing Acrobat Standard DC in our Citrix environment. I managed to create a prov.xml file and thats placed on the imaged server.

Everythign seems to work fine, except for one thing. We dont want our employees connecting to Cloud solutions and Sharepoint I disabled all these setting with Registry settings.

These options are no longer available on the start screen, and in any of the menus.

After about 30 second of having Acrobat open Im getting a "sign in with your Adobe ID" popup, which is driving me nuts.

Is there any possibillity to disable that splash screen?

Ive found a solution here:

Disable Adobe Sign-in - Acrobat DC - Super User

but since we dont use packaging for installing, this isnt a viable solution for me.
