VL53L7CX blinded by retroreflective surface

I'm using several VL53L7CX sensors in a robotics application.  They work well except for when a retroreflective surface is present, which blinds the entire sensor, including SPADs not pointed at the retroreflective surface.  A large retroreflective area is not needed, only a few cm^2 patch.

This is a big problem for us since industrial environments are full of retroreflective surfaces (e.g. safety vests, markings on the ground, etc.).

I'm currently using the default values for sensitivity, sharpener, etc.  Any parameters you recommend tuning/adjusting to make this sensor more robust?
