Disable EA Overlay through Config File or Windows Registry

I have added an EA Game to Steam as a Non-Steam-Game to play it with the Steam Overlay but I noticed that some games freeze on start when both the EA and Steam Overlay are active.

Example for one game: STAR WARS Galaxy of Heroes.

I can manually disable the EA Overlay through the app but this option is a global setting and not an individual game setting like it was in Origin.

Is it possible that I can disable the EA Overlay through a certain config file or a certain entry in the Windows Registry(if available)? In that case I would run a batch script that disables the EA Overlay through that file or registry entry when I run an EA Game from Steam as a Non-Steam Game to avoid issues with the EA Overlay and reactivate it once the Non-Steam-Game is closed.

If someone could help me with this, it would be much appreciated.
