Hello,
You can use phpdocx 10 with LibreOffice 7, except generating hyperlinks with active links that requires using an existing character style (feature supported since phpdocx 11 in addLink, embedHTML and replaceVariableByHTML methods). On https://www.phpdocx.com/documentation/conversion-plugin/preparing-the-templates-for-its-conversion (Preparing the documents for conversion when using the LibreOffice method section) you can read some recommendations when using the conversion plugin based on LibreOffice.
Regards.
