VL53L1X Long-distance Ranging sensor: I have planned to integrate this sensor into my board. How is the I/O supply of 1.8V (standard mode) generated internally from the AVDD supply? Will there be any issue when I provide 2.9V (or) 3.3V supply to AVDD?

On my board, I have two supply options within the permissible range of this sensor (2.6~3.5V) i.e. 2.9V & 3.3V. Will there be any switching noise coupling to the power supply due to the ranging operation of the sensor? Are there any recommendations to mitigate noise coupling?

I don't know how the power is generated - only that it is and there are no issues.

The sensor creates it's own voltages internally from what you give it.

I've not heard of any complaints about noise coupling.
