What makes you think the two are connected in any way?
Under bullseye, if the ntp package (which supplies the ntpd program) is
installed, then systemd-timesyncd is removed. The two packages will not
coexist.
Under some older versions of Debian (I'm not sure when it changed exactly),
they can coexist, but the systemd-timesyncd service is configured not to
run if /usr/sbin/ntpd exists and is executable.
Either way, if ntp(d) is installed, systemd will not do anything regarding
time synchronization or NTP.

This is too vague. What are you actually seeing?
unicorn:~$ ps auxw | grep ntpd
ntp 758 0.0 0.0 74696 3896 ? Ssl Feb04 0:14 /usr/sbin/ntpd -p /var/run/ntpd.pid -g -u 107:112
greg 290127 0.0 0.0 6244 2404 pts/0 S+ 15:04 0:00 grep ntpd
The ntpd program (service) isn't started with an NTP server address as
an argument. The configuration is all in files.
unicorn:~$ grep -e ^server -e ^pool /etc/ntp.conf
pool 0.debian.pool.ntp.org iburst
pool 1.debian.pool.ntp.org iburst
pool 2.debian.pool.ntp.org iburst
pool 3.debian.pool.ntp.org iburst
Are you claiming that systemd has somehow modified your /etc/ntp.conf
file? What change did it make? What does your ntp.conf file look like
now, after the change?

Huh? You're saying that removing the "-u $UGID" option made it "work"?
And that it "didn't work" with -u being passed?
Why would that be the case? Is there a file or directory on you system
that has the wrong ownership?
What errors were you getting in your logs?
