strange; I just tested it with

--- connman.service ---
[Unit]
Description=Connection service
After=syslog.target
Wants = connman-env.service

[Service]
Type=dbus
BusName=net.connman
EnvironmentFile = -/run/connmand.env
ExecStart=/usr/sbin/connmand -n $CONNMAND_OPTS

[Install]
WantedBy=multi-user.target

--- connman-env.service ---
[Unit]
Before = connman.service
ConditionKernelCommandLine = root=/dev/nfs

[Service]
Type = oneshot
ExecStart = /bin/sh -c 'echo CONNMAND_OPTS=\\"--noipconfig=eth0\\" > /run/connmand.env'

[Install]
WantedBy = connman.service


which works fine. Of course, this is just a quick hack and needs some changes
(replacement of inline shell script, perhaps setting RemainAfterExit, using
'systemctl enable' instead of 'Wants = connman-env.service')
