I see this that looks possibly interesting:

Feb 23 06:50:43 SERVER systemd[1]: Reached target Network is Online.
Feb 23 06:50:43 SERVER systemd[1]: Mounting /mnt/NFSSERVER12_VOL...
<snip>
Feb 23 06:50:43 SERVER systemd[1]: Starting LSB: RPC portmapper replacement...
<snip>
Feb 23 06:50:43 SERVER systemd[1]: Starting LSB: NFS support files
common to client and server...
<snip>

So it looks like systemd is starting the mounts in parallel to
starting the nfs support infrastructure.

What happens if you add the following content:

[Unit]
Wants=remote-fs-pre.target
Before=remote-fs-pre.target

To snippets for nfs-common and rpcbind ? That would be
/etc/systemd/system/{nfs-common,rpcbind}.service.d/00-remote-fs-ordering.conf

Ensure systemd is picking up the files by issuing a systemctl
daemon-reload, and then doing systemctl cat rpcbind nfs-common and
making sure the output includes the snippets.
