Show us the systemd unit file, or a URL that points to it exactly as it
appears on your system. (Hint: if it's a Debian package, and if you're
using the unmodified Debian systemd unit file, you might be able to
find it on sources.debian.org. If this is the case, tell us what version
of the Debian package you're using. For example, buster's is at
<https://sources.debian.org/src/prometheus/2.7.1+ds-3/debian/service/>.)
It might also help if you try "systemctl status prometheus" (or whatever
the unit's name is) and show us what it says. Just in case the systemd
unit is merely a thin wrapper around a sysv-rc script, as is sometimes
the case.
It's worth noting that the Debian /etc/default/prometheus file from
buster's package
(<https://sources.debian.org/src/prometheus/2.7.1+ds-3/debian/default/>)
explicitly sets a variable named ARGS.
