I wonder how far those profiles really go.
FWIW, if you check "Enable Profile Corrections" and then select "None" as the "Make" the message changes to "Unable to locate matching profile" from "Built-in lens Profile applied." But there is no visible difference in the displayed image.
If you are feeling rather hardcore, there is a text header in raw files that can preset a number of parameters including automatic corrections. I used to do that to get LR to accept non-supported files formats. If you go mucking around there you might be able to turn off the auto profile, I don't off hand known exactly what how to do that.
Also FWIW, I find I get much better edge sharpness when I set "Lens Corrections->Manual->Distortion" to some negative number between about -10 and -24, depending on the lens. This re-introduces the barrel distortion that the automatic profile correction may have removed at the price of adding edge distortions. You lose a bit of image around the periphery, but edge sharpness goes up, especially if you're stitching. Go figure, but it seems to be the case.
