UAD Neve 1073...less usage if not using preamp section?

I was wondering if, like the API Vision, if some functions are bypassed if the plug-in uses less CPU? Like, can I insert just the EQ section, and bypass the preamp, like if I was mixing through the line input? That thing is a hog, and even though I have a Octo, I'm worried I'd be bogged down using a couple instance of it in a typical 24-ish track count session
