This shouldn't be a thing. It really doesn't matter nowadays. You can send your resume and nobody will care.
Plus, you do realize you're categorically ruling out a company by projecting one trait onto their entire culture, for the crime of using an arbitrary signaling factor?
I usually don't do that, but I can't tolerate this kind of rigidness with old habits.
If it were a junior role, and they only had bootcamp experience, then I'd consider it.
