Didn’t see any active one, but this is very rare to found.
Carpenter bees make perfectly round holes a little smaller than a dime. Never seen all that frass around a carpenter bee hole. I’d say not.

Where is this located?
Did you tear up the area & wood, or is this exactly how you discovered it?

Look up “carpenter bee damage” on Google images.
I think it’s carpenter bees. Had them in Jersey at my childhood home. “Apparent damage from wood destroying organisms/insects.”

The property is at central Jersey. The hole is perfect round. I really don’t have any idea about the frass. another photo attached.

Plenty of carpenter bees in my area. Actually have them on my deck and see this all the time. Based on the photos, the holes, boring and frass are consistent with carpenter bees.

Yes, carpenter bees. I see them all the time. The larger oval shaped holes are from woodpeckers.

I Replaced this trim recently, and there were carpenter bees inside the wood. You can hear them buzzing and feel them vibrating the wood.

Carpenter bee entry holes in wood trim are almost perfectly round but often the tunnels become exposed as lengthwise holes in the surface. Here it may be different because of that plastic or whatever it is. I’d guess that because the tunnels in the photo appear to have the faint outlines of compartmentalized larval chambers in the tunnels typical of carpenter bees, it’s almost certainly carpenter bees.
