If you deploy via GPO / GPP, you can edit the $Update, line to say $Update = $true if necessary. You can test it on your workstation by running interactively with the -Update switch. I make attempts to back up the registry into a new value, but as with everything, please test before deploying. If users aren’t administrators on their machines, you may need to split the HKCU piece into a user logon script to ensure they don’t generate errors when trying to modify the registry.
You can save it and drop it in a computer startup script as well as a user logon (since the script modifies both HKLM and HKCU). Today, I was asked about manually disabling the Skype of Business Outlook plug-in for a customer where users have both Skype and Teams clients and are configured in Islands mode.
