Debian 10.3: X does not start

In most cases there is no need to run "-configure" since X can autodetect
many things using defaults provided by distro.
Have you tried official debian wiki (it is about amdgpu, not general
modesetting)
https://wiki.debian.org/AtiHowTo ?
I think that "/dev/dri/card0: No such file or directory" means there is no
kernel driver (no module compiled or not loaded by udev)
Do you run custom kernel? Have you tried to load module manually using
(modprobe)?
