qbittorrent seems to lack torrent version 2 v2 or hybrid torrent creation

I had both with archlinux.
Why can't I create hybrid or torrent v2 in qbittorrent 4.5 on freebsd 13.1 amd64?

ps let me know if this is wrong section to post
 
The port and packages (default, nox) of net-p2p/qbittorrent are configured by default to version 1.x. For version 2.x it needs to be reconfigured. But it looks like version 2.x is unstable:
Rich (BB code):
/usr/ports/net-p2p/qbittorrent % make showconfig
===> The following configuration options are available for qbittorrent-4.5.0:
     DBUS=on: D-Bus IPC system support
     DEBUG=off: Build with debugging support
     PYTHON=off: Install Python to support some plugin functionality
====> libtorrent version number to use: you can only select none or one of them
     LIBTORRENT1=on: Version 1.x (default)
     LIBTORRENT2=off: Version 2.x (unstable, has memory issues)
===> Use 'make config' to modify these settings
