there is no non-gui installer.
OOOOps. Yep coyottito, there is.
I think, (been awhile since I have done a fresh install) , Anti even incorporated a cli install option also in AntiX 11 Base and Full Iso grub menus also. It won't be in 8.5 (though I seem to remember a 8.5 core iso also) but is included in AntiX 11.
