To ubuntu 22.04, I refer to https://roll.urown.net/desktop/network/time-sync.html. Using NM's dispatch scripts, NetworkManager can talk with timesyncd when configuring to use internal dhcp client.
If want to use dhclient's hook, I think you should configure NetworkManager to use dhclient. [main] dhcp=dhclient
I don't test it, just for your reference.
