I would split the cmdline generation into a dedicated one-shot service;
e.g. modify the original connman.service to have something like

  [Service]
  EnvironmentFile = -/run/connmand.env
  ExecStart=/usr/sbin/connmand -n ${CONNMAND_OPTS}


The '/run/connmand.env' is created by a service with

  [Unit]
  Before = connman.service
  ConditionKernelCommandLine!=root=/dev/nfs
  
  [Service]
  Type = oneshot
  ExecStart = /usr/sbin/create-run-connmand.env

  [Install]
  WantedBy = connman.service
