Tethering - without using camera preset?

I normally have LrC set with a Raw Default based on my camera (Sony A7rV). This does a few things like set my preferred sharpening, some basic exposure settings, etc. This is all fine when I use my camera normally, i.e., take pictures and import them.

But, sometimes I use tethering when I use the camera for scanning negatives for further processing with Negative Lab Pro. It's about the most efficient workflow. In that case, I don't want this preset/default applied. There is no apparent way to turn that off or apply a different preset during tether like I can do with Import. Or am I missing something? Do I really need to go to preferences and turn off specific camera raw defaults and make Global a different preset that zeroes out nearly everything? It would seem better if the tethering window had a way to override that.
