connect multiple sensors mlx90614

Hello, I'm new to this issue of the i2c, well my question is how to change the direction of the sensor to read several times, the default address is 0x5a I would like to change it so that multiple sensors can be read according to the datasheet (https : //www.sparkfun.com/datasheets/Sensors/Tem ... rev001.pdf) the address for the smbus address is 0xEh ok, but when I try to change it I get an error, the truth is not that I know much what I'm trying to do, this was what i2cset -y 1 0x5a 0xEh 0x55.
the error says something like the address I'm trying to enter is incorrect and says something about the PEC

I do not think i2cset can chamge the i2c address of a device. Rather create additional i2c busses on other gpio pins
