OnlyOffice integration in combination with PDF preview

Hello

I am running Seafile pro 7.1.14 (docker).
I started just using the native pdf preview, which works well.
I have then installed an OnlyOffice server and integrated it with Seafile – again, all working very well.

Now my question is: is there a way to still use the native PDF preview instead of opening OnlyOffice, especially when a user does not have edit rights ? Typically very valid for a Published library.

The goal is to reduce the load on the OnlyOffice server which does require some CPU and RAM, but also to reduce license consumption which definitely has a price.
