Well, that is what happens actually, at least in my vm.

When I don't have chrony installed, timesyncd is running:
root at bionic-chrony:~# systemctl status systemd-timesyncd chronyd
Unit chronyd.service could not be found.
● systemd-timesyncd.service - Network Time Synchronization
   Loaded: loaded (/lib/systemd/system/systemd-timesyncd.service; enabled; vendor preset: enabled)
   Active: active (running) since Wed 2018-07-04 19:40:37 UTC; 13s ago
     Docs: man:systemd-timesyncd.service(8)
 Main PID: 521 (systemd-timesyn)
   Status: "Idle."
    Tasks: 2 (limit: 1152)
   CGroup: /system.slice/systemd-timesyncd.service
           └─521 /lib/systemd/systemd-timesyncd

The moment I install the chrony package, timesyncd is stopped:
root at bionic-chrony:~# apt install chrony

The following package was automatically installed and is no longer required:

Use 'apt autoremove' to remove it.

     Docs: man:systemd-timesyncd.service(8)

   Status: "Idle."

and chrony is now running:● chrony.service - chrony, an NTP client/server
   Loaded: loaded (/lib/systemd/system/chrony.service; enabled; vendor preset: enabled)
   Active: active (running) since Wed 2018-07-04 19:41:23 UTC; 37s ago

    Tasks: 1 (limit: 1152)
   CGroup: /system.slice/chrony.service
           └─1371 /usr/sbin/chronyd

both are seen as enabled, but just chrony is running:
root at bionic-chrony:~# systemctl is-enabled systemd-timesyncd chrony
enabled
enabled

This state is kept after a reboot: timesyncd stopped, chrony running.
