If you don’t want to include the users it is not possible when exporting a project with its configuration and its data. Users will be included in the exported zip file, if you want to remove the users in the exported zip file you will have to unzip the exported zip file by downloading it and manually edit the configuration files in which users are included in the exported zip file. The configuration files which users will be included are config.xml, entities.xml, and activeobjects.xml. You have to manually remove the user entries which you don’t want from these XML files.
But, editing those XML files might corrupt the complete zip configuration itself.
But before making any changes to the XML files, please take a backup and then perform the changes. After removing the users who are not part of the particular project, and then zip the export file. Also, ensure that the zip file's hierarchy should be as shown in the screenshot below.
