I want to drive two BNo055 orientation sensor with my arduino but when I attempted to change the I2C address on one of the sensors so that it becomes 0x29, it instead changed to 0x40. Form looking online it appears that this is HID-I2C. How do I switch it back to normal?

Bno055 i2c address is 0x40 but why

You are right, see the Bosch datasheet Table 5-1: Pin Description.
I2C is selected by both pins connected to GNDIO. GNDIO should be connected to GND on the board.
