Not for me Hank.
I do these mounted on a flat piece of alloy with doubled sided tape, that tape lasts for about 8 pieces before I have to replace it.
If I drilled I'd have to clean all the thru drill holes after every piece to make sure the next board was nice and flat.

Engrave one board, swap boards over, 10 seconds and then drill whilst it doing the next, drilling takes no time at all, I'm always waiting for the router, not the other way round.

That same alloy plate is good for any board that fits it, thru drilling means I have to have different plates and setting up for a new job is fraught with danger if the holes don't line up. only takes the drill to hit the side of a hole in the plate to break it.
