it depends on how the DPI kit is connected to the network.

if you connect a dpi kit to a spare port on the network switch and setup port mirroring it will monitor without interception, a bit like you having a conversation in a shop and a person listening near by, they can listen but not alter the conversataion. (this setup can only listen and not change or inject data into the data stream)

if it sits in the data stream and the data has to go physically through it like playing chinese whispers, the message at the end of the change may have been altered on the way, this is interception, subtle difference (this setup can listen and change or inject data into the data stream)
