Changing Self Installation option or Available Applications on already deployed Creative Cloud

We have deployed Creative Cloud as a full suite and allowed users to install whatever they want. This was working great until Adobe randomly switched Acrobat from being a 32bit deployment to 64bit and we have plugins that aren't compatible. We spoke to Adobe about this and they said they didn't change anything and have no idea why we are getting 64bit although I see other posts out there about the same thing.

Regardless we now need to replace all 64bi versions with 32bit which is easily enough and mostly done, but now how do we block thew 64bit Acrobat without having to reinstall Creative Cloud on 3000 devices and this will fdorce users to reinstall all their apps which is not viable to the business.

We have application whitelisting software in place but somehow Adobe bypasses any Blocks I put in on the install, I can see the Block work if I manually try and install the exact same app but if CC installs the app it must use SYSTEM or something that gets passed the whitelisting software.

My questions to any experts out there are, is there a way to change either to available apps on an already installed version of CC by modifying a config file somewhere or just reinstalling the CC Desktop App without changing the apps installed? If not is there a way to turn off the User Managed Installs and we will elevate installs using our Application Whitelisting Software instead which gives us back control?
