Fitbit Sense settings for scanner intensity

[Pronoic]

I'm trying to find the settings for how often the Fitbit sense reads my biometrics and not having any luck finding it in the app settings or the device settings. When I first set it up about two three months ago I set it for the highest frequency. About 5 or 6 weeks into owning it and wearing it I noticed that my skin underneath where the Fitbit sense normally sat was getting "old," kind of wrinkled, and it was quite alarming. I stopped wearing it. I assume it is due to the UV radiation from the device. I also assume that if I set the frequency of reads to the lowest possible I'll be able to prevent that damage to my skin.

Anyone know where I can find deets for accessing the ancient wisdom of Fitbit Sense scanner settings?

I have never seen such a setting anywhere.
