Well, I dont think nintendo would put a one tap homebrew button, but an RCM mode setter. But is there any way to get into RCM mode?You think nintendo would just put a button inside the console so you can hack it with a single click?
Seriously now for v1 patched/v2/oled/lite modchip is the only option. Unless it's running some super low fw (lower than 4.1.0) you're out of luck.
