How do I get rid of this stupid freaking thing?

(Android 16) I have auto-rotate disabled manually, my phone should be locked in portrait mode at all times. Yet somehow, whenever the slightest bit of rotation is detected this dumb banner pops up in the top right corner. It’ll cover up a button I’m trying to use, I’ll accidentally hit it and the phone will lock itself into landscape orientation. Then I’ll have to close everything. Grrrrr.

Is there a way to disable this modal? Or is it a built in annoyance?
