Some cars have a handy dial that can be turned to stop alarms sounding when too many molecules are impacting the car at night—my problem.


Searched under dash for a likely looking dial—no go.
Searched this forum for mention of such a thing—no go.
I suppose Volvo elected against including this.


Advice?


Note: not a check engine message problem.

You don't have "too many molecules hitting your car". You likely have a fault, like a bad siren.
