The place to start, after putting the GeForce back in, is to try doing something.
There should be some BIOS setup option to prefer the GPU that is on a card
installed in a slot instead of the IGP. Whatever the BIOS has that can lead it
away from using the Kaveri IGP should be tried before trying to blame any software
for the black screen.

Best to start with a clean sheet. At the Grub menu after striking the E key,
remove everything on the linux line following ro. If it solves, add back each of
the others you wish used one at a time until the problem returns. If it was here
I'd probably start by removing only reboot=pci, radeon... and amdgpu....

Unless that card is in fact defective in some way, it should be usable. I retested
my NVIDIA GT218 [GeForce 210] to confirm its behavior typifies other cards WRT
connectors used, which is that xrandr treats as primary port that connector which
is physically closest to the motherboard. If yours is like mine, that means the
DVI connector is most preferred. Next is the HDMI. When VGA is the only connector
used, xrandr reports no primary label. This means best results, or any results
with only a single display in use, may require using a DVI (first choice) or HDMI
cable (second choice).

Is another PC available to connect to it via ethernet or wireless, so that a
remote login can be tried to see if boot completed and the fault is only the black
screen?
When you reached the black screen, did you try Ctrl-Alt-F2,
Ctrl-Alt-F3...Ctrl-Alt-F6? IME, post-init content of vtty1 isn't necessarily
determinative in Buster of whether boot succeeded, and only the login manager or X
is the blocking culprit.
