Is there a magic code that will reset the Teensy 4.1 to program mode?

I have used _reboot_Teensyduino_(); and SCB_AIRCR = 0x05FA0004; in the past, but these don't work for the Teensy 4.1.
 
That should restart an ARM Teensy.

This should put it into bootloader:
Code:
asm("bkpt #251"); // run bootloader
