I am sure that all the AMT Intel board like dq965gf, dq35jo, dq45ek,dq45cb (All 'Q' chipsets boards) support virtualisation.
Usually, the Intel VT is found in the BIOS >> Security Option
I am 100% sure that the board DQ45CB and other AMT boards have this option in the BIOS
Now make sure to check the CPU compatibility for each AMT Boards.
All the best,
