Is it possible to have several L3GD20H on the same SPI bus?

Is it possible to have several L3GD20H on the same SPI bus (running SPI mode)?

The datasheet says that if chip select is high the circuit goes to I2C mode.

So by selecting one chip with chip select low and the other

chip selects are

 high, the other chips would enter I2C mode and screw up the communication?

In register LOW_ODR (39h) there is a bit I2C_dis. If you set that to 1 you will disable i2c and only use SPI. I haven't tested it myself since I only have one sensor but I believe it should give you what you want.
