How to set Adobe Neutral instead of Color as the adobe default profile for importing?

Having taken a bit of time to search and read the help pages, 

I'm having trouble with my learning of lightroom classic, current version - when setting import preferences, I can set the profile as 'Adobe default' - but I can't see where I can specify that for the default Adobe profile I want Neutral , not Color, which for me is a better starting point. These profiles are not in the presets section. 

Thanks anyone!
