How to completely disable black screen and clock-page on CentOS 8 console (before login)?

I want my screen to stay EXACTLY the same after it's finished booting, forever, which means I NEVER want it to go black, and I NEVER want to see that clock overlay appearing over the top of my username selection login dialog (it's a VM - has no real monitor, so all this blanking and screen saving garbage makes no sense). Basically - when something goes wrong, like a kernel problem, I can't see on the console what that was, since it's gone black and only shows up if a key is pressed, which (in the case of kernel issues) doesn't always still work.

I've already included this on my boot line: consoleblank=0

I've tried this:- gsettings set org.gnome.desktop.session idle-delay 0

I've even tried this:- rm -rf /usr/bin/xdg-screensaver /usr/lib/python3.6/site-packages/orca/scripts/apps/gnome-screensaver-dialog /usr/lib64/libxcb-screensaver /usr/lib64/pkgconfig/xcb-screensaver /usr/lib64/totem/plugins/screensaver /usr/libexec/gsd-screensaver-proxy

I'm in runlevel 5 - I'd prefer not to go back to 3 ( which consoleblank=0 works for ).

Anyone got any clues? Basically - I never want to see this timewasting dumb idea againi.sstatic.net/wQcu2.png
