I usually just admin down the eMTA interface. You can SNMP walk the CM to find the correct index number, then admin down the interface in the CM config file.
From SNMP walk:
IF-MIB::ifDescr.16 = STRING: PacketCable Embedded Interface
In CM config file:
SnmpMibObject ifAdminStatus.16 Integer 2; /* down */
EDIT: I forgot to add you would SNMP walk for "ifDesc" to list all interfaces description in the CM.
Another option, if you do not want to add anything into your config file, set DHCP Option Ip address of MTA to 0.0.0.0 in DHCP Offer. MTA will have to shutdown when the IP 0.0.0.0 is seen in the reply.
How can i set option 122 to 0.0.0.0 to disable mta to every docsis modem.
Can you please post any example of isc-dhcp-server because i'm getting to many request from MTAs and currently i'm not provisioning MTA's.
host cm {hardware ethernet AC:B3:13:1x:xx:xx; fixed-address 10.105.4.18; filename "CM820S-64M"; option option-122 0.0.0.0;}#
For every cm with mta. You'll need also global configuration for option-122 - find in forum archive.

Thank you guys. I was looking for something like THomson has:
tmmCmMtaDevice
Value list: 1: disable(0)
2: enable(1)
