Minimum connection requirements of VL53L1X Time of flight

Hi there

I want to use this with my Pi but I don’t have pin 7 (GPIO4) available, at least not without considerable effort! It’s labelled INT on the VL53L1X board. I was under the impression that this module is I2C only and thus only needs two signal lines.

My questions are:
What does the INT pin actually do?
If it’s important, can I use another GPIO pin instead?

Thanks
