Pi3 does not expose the SoC's DSI0 interface, only DSI1. Only Compute Modules and Pi5 have a dsi0 interface exposed on a connector.
Use the 6.6 kernel and Bookworm - 6.1 and Bullseye are only getting basic security updates when really needed.
vc4-fkms-v3d will not work with 3rd party displays as it is still using the firmware display stack.
On Pi0-4 you won't get a new /dev/dri or /dev/fbN device for a DSI (or DPI) panel, just a new connector under the vc4 DRM driver. Only separate DRM drivers get additional /dev/dri and /dev/fbN nodes.
There are a number of DSI panel overlays in https://github.com/raspberrypi/linux/bl ... /overlays/
cutiepi-panel-overlay.dts is probably one of the simplest as an ILI9881 based panel. You can initially ignore all the backlight and touch references as they are ancillary to the panel operation.
