I too have been miffed about Auto lens profiles being applied in both Lightrooom and Photoshop; with absolutely no way of disabling it.
I shoot extensively with an Olympus 8mm lens so very often I am wanting distortion.
At last I discovered Olympus Viewer 3, you can TURN OFF lens information on Olympus raw files.
In RAW2 edit section / Distortion Correction / Manual -uncheck the "Use Lens Information" and adjust manually the distortion on a plus or minus scale.
What a brilliant way to dial in your preference as you intended, I rather think it may only be for Olympus users?
