Betaflight unified target for this FC also lists BMI270. This FC is probably a victmin of the chip shortages and was shipped with any imu they could get their hands on.

Betaflight unified target has a total of 3 gyros for this FC (mpu6000, bmi270 and ICM42688), but it also lists 2 CS pins (gyro1 and gyro2).
Gyro2 cs is PC3. Both are connected to SPI1. There is no way to tell from the target which gyros may be connected to which CS pins.
Hard to tell if this is a mistake on the target or a case of multiple board revisions/layouts sharing the same target in BF.
