On my servers I want to completely get read of graphical boot. I do not like fancy graphics that are not compatible with my basic Matrox integrated card and I do not want my system to start directly in X and load the server with unwanted stuff.
STEP 1: Remove graphical boot
Completely un-install the dreaded plymouth as root.
dnf remove Plymouth*
STEP 2: Set the system as a multiuser with no graphical X as default
As root do the following
# systemctl set-default multi-user.target
# systemctl get-default
STEP 3: In case you need at some point the graphical X for some operations you can use the old way of starting X as a simple
startx
