I've been trying many combinations of xorg.conf variants and output connections. 
I found a setup which starts correctly with one 2880x2560 screen across two 
2560x1440 monitors in portrait mode.

                       ,-------------------,
  Left monitor   DP-4  3                   |
  Right monitor  DP-0  2   Quadro P400     |
                 DP-2  1                   |
                       MMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMMM Motherboard

But this is unstable.  Without activity on my part the screens blank, and when I 
hit a key, the setup is now 1440x2560 on the left monitor only. File 
/var/log/Xorg.0.log reports:

There seems to be a basic instability in Quadro P400 + Nvidia 460.91.03.  I have 
seen spontaneous changes from 1440x2560 to 2560x900 or 480x640, spontaneous 
rotations, and refusals to return from power-saving blanking.  Ctl-Alt-Keypad-+ 
has no effect

I followed your example, bought an Nvidia GF119 [NVS 310] for 41€, removed all 
the nvidia packages, removed xorg.conf, installed the NVS 310 and restarted the 
machine.

I got a perfect 2880x2560 screen across the two monitors.  I can slide windows 
from one monitor to another. but I didn't get much work done.

nouveau froze after 11 minutes.  dmesg reports;

I searched at https://www.debian.org/distrib/packages#search_contents for 
nvd9_fuc084 but found nothing.

I downloaded file firmware.tar.gz from
https://cdimage.debian.org/cdimage/unofficial/non-free/firmware/bullseye/current/
but couldn't find any nvidia firmware.

Where can I get the required nouveau/nvd9_fuc084 ?
