I have a home server where I installed BRLTTY in the case I would have to

Debian Bullseye is installed on this machine.

Is it possible to have it started only when I plug my braille display on an
USB port instead of starting it on boot with the SystemD unit?

I think starting only when the braille display is connected is the
default for BRLTTY nowadays. It uses udev rules to detect the presence
of the display by matching the USB vendor and product identifiers.

I don't know why yours isn't configured to start this way, however.

I've just purged brltty then re-installed it, with the same result.
The systemd service is launched, udev does not seam to be used to start BRLTTY.
Is there some dependencies not included with the brltty package which have to be installed?

    As a precision, I have no brltty related file in /etc/udev.
    It looks like Debian does not manage at all this way to run brltty
    in Bullseye and it is the same with the version available in
    bullseye-backports.
