@ahi technically, it is. I know this because I have a lot of experience burning things in my instant pot.
The burn notice is just a temp sensor on the bottom, and when it goes off bc the bottom is too hot, it turns off the heating element. If you've got it pressurized, I have found that it turns back on once the bottom cools a bit and things keep cooking as normal. If it goes off while you're trying to get it pressurized, you're screwed.
