Veeam Backup for Microsoft 365 • Possible to upgrade a Proxy manually?

I have not yet made a support ticket on this yet, but I having issues with updating 2 proxies from the Veeam for Microsoft 365 Server, it stops on the error "The process cannot access the file
'\\server\Admin$\Veeam\Backup365Proxy\UpdateServices\Service\e_sqlite3.dll' because it is being used by another process." (it's locked by the update service, so this is weird).

Anyhow, before I make a ticket for this, is there a way to manually update the proxy, using the sources files on the main backup-server? I noticed the files under "C:\Program Files\Veeam\Backup365\Packages\Proxy" appear to be the source files for the Proxies?
