i2c is a shared bus, you can have multiple devices as long as no two devices have the same address. That will happen if you connect two VL53L1X sensors to the one i2c bus that are at the factory settings.
Too get around this most of the Breakout Garden breakouts have a jumper on the back to change its i2c address. You do that to one of them and your good to go.
On that breakout it looks like you run the change-address.py script on “one” of them. Once you do that they will each have a different address and work on the same i2c bus.
Once you have changed the i2c address on one of them you just wire them up in parallel to i2c and power. You’ll have to edit the example and or your py file for two sensors.
