Server Side for Google Optimize?

Is there a way to integrate Google Optimize so it is server side for split testing? I searched forums and don’t see an answer for this. I know that you can enter the container ID in settings but is there a better way to implement that would make it server side? Any feedback or knowledge on this would be appreciated. Thank you.

For server side you need server access first. Webflow not provides this. Take a look at my several last posts, with that you can get server access.
