Can we run SharePoint 2016 sites in SharePoint 2010 mode?? I can see Hive 14 in SharePoint 2016 installation, but while creating a site collection that option is not coming? Please help

“SharePoint Server 2016 does not support SharePoint 2010 mode (that is, compatibility level 14) site collections. Any site collection that is in this mode will block the attachment of that content database to the SharePoint Server 2016 farm. You must upgrade all SharePoint 2010 mode sites to 2013 mode (that is, compatibility level 15) on the existing 2013 farm before you mount the database on the new SharePoint 2016 farm”
