Teensy 4.1: Do I need to use a knife to sever a circuit for simultaneous power/usb?

[Hitachii]

Hello,
I've seen that the other teensy boards need to be cut in a certain place using an xacto knife in order to power the board and use USB at the same time. Is this the case for the Teensy 4.1, and where can I find the place to cut? Thank you!
