After some more messing around and researching, I managed to put it somewhat together with the dietpi tool and commands.
The “disable-wifi” didn’t look right and I believe is a bug from when updating the PI and modifying the displays. I went back and chose the correct resolution which fixed the display issue. I also ran the wrong command originally as well:
~$ grep -E 'max_framebuffers|dtoverlay' /boot/config.txt
#max_framebuffers=0
dtoverlay=disable-wifi
dtoverlay=vc4-kms-v3d-pi4
~$ sudo ls -l /dev/fb* /dev/dri
