There is no T2 chip on the new Mac. The security functions are all integrated into the SOC itself and it uses a newer, different design. The T2 used an older A10-derived design, which had been compromised years ago and it was made worse because the physical design of the chip's connectivity to the other hardware made it easy to compromise. The M1 integrates everything on the chip, so there is no physical attack vector and the software is independent from the system board itself, so there should be no easy way to break in.
