Can you reproduce that condition and then get the output of "systemctl status NetworkManager-wait-online"? That should confirm that the ExecStart process does not include the -s flag.
Here it is:
systemctl status NetworkManager-wait-online .

but still:

The setup of this server is:
eth0 static IP declaration with dns servers and gateway eth0.2006 static IP declaration: additionnal vlan interface
with the associated port on a cisco switch configured as:
switchport trunk native vlan 390 switchport trunk allowed vlan 390,2006 switchport mode trunk switchport nonegotiate storm-control broadcast level 5.00 3.00 no cdp enable
/etc/resolv.conf was generated by NetworkManager at the same second indicated by nm-online:

The 'Y' server is in the eth0 subnet.
'Y' has to be resolved by the DNS.
As said before, even pinging the gateway IP succeeds only more than 20s after the routes (as seen by "ip route") are defined.
Weird no?
Cisco switch and that delay for traffic on a static address?
Sounds like symptoms of STP delaying s port from listening to forwarding...
Have you looked at disabling on that interface or setting portfast if it's only host facing?
