Indeed. From the man page:
-m retry-time
    Specifies the length of time, in minutes, to continue retry‐
    ing  notifications to unresponsive hosts.  If this option is
    not specified, sm-notify attempts to send notifications  for
    15  minutes.   Specifying  a  value of 0 causes sm-notify to
    continue sending notifications to unresponsive  peers  until
    it is manually killed.

    Notifications  are retried if sending fails, the remote does
    not respond, the remote's NSM service is not registered,  or
    if  there  is  a  DNS  failure  which  prevents the remote's
    mon_name from being resolved to an address.

So rpc-statd-notify.service should be fine with being started before
the network is up at all.
