Xfce install Gnome as dependencies

Hi, I have installed Freebsd 13.2 on my laptop and seems to work fine.
Then I have installed xfce DE with
pkg install xfce
and LightDM as login manager.
After reboot I found that Gnome and Xfce are both installed.
How can I install only xfce? Thanks
Gnome isn't a dependency of XFCE but some parts of Gnome are (dconf, GVfs, etc). Mostly because of some compatibility settings in various parts.
