Assuming you are on Debian/Ubuntu.
1) sudo pg_ctlcluster stop 14 main_old
This will stop the server for this session
2) sudo vi /etc/postgresql/14/main_old/start.conf
Change auto to manual.
This will keep the server from restarting on reboot.
You can still start it using
sudo pg_ctlcluster start 14 main_old
Though if you want to do that then:
vi /etc/postgresql/14/main_old/postgresql.conf
and change port to something other then 5432.
3) If you have determined you really don't need that server and have all
the data safely backed up or moved to the other server, then(THIS IS NOT
REVERSIBLE):
sudo pg_dropcluster 14 main_old
