Just adding some thoughts to expand on Amit's comments...

You can do it but there are some caveats, like Amit stated.  With directory sync, the source of authority becomes the on premises AD.  For changes to mailboxes to be supported from on premises, an Exchange server must be installed; but you do not need to configure the server for hybrid--though it will help.  If you have any O365 subscription, the Exchange hybrid product key comes with it.

You will get your choice of hybrid key to request ... Exchange 2010, Exchange 2013, or Exchange 2016.  If you choose 2016, your forest and domain functional level must be set to Windows Server 2008, at a minimum.

The server that will have directory sync installed must have a 64-bit OS installed for password sync and that OS must be Windows 2008 R2 or newer.

You need to setup hybrid environment. For that you need to have on-premises server. There is no such plan, required for hybrid.
