The man page on add_install_client has a clue:
-b property=value
Set a property value in the client specific bootenv.rc
file located on the boot server's TFTP directory,
/tftpboot by default. Use this option to set boot pro-
perties that are specific to this client. You can use
the bootpath property to automate the selection of the
boot device instead of manually using the Device Confi-
guration Assistant. You can use the boot-args property
to automatically select a jumpstart installation. See
eeprom(1M).
It could be more explicit, but typically you're looking for a file of
the form:
/tftpboot/<dhcp client id>.bootenv.rc
<dhcp client id> is, by default, constructed as a hex string consisting
of the media type code ("01" for Ethernet) plus the network interface
MAC address; it must be all-caps and must be zero-filled. So for
example, a system with an Ethernet network interface MAC address of
0:a:e4:34:30:7 would have a DHCP client id of 01000AE4343007.
And no, you don't need to run any commands after modifying the
bootenv.rc file; it will be automatically downloaded with tftp on the
next attempt to network boot the client.
