Optimized battery charging notifications

I don't mind that the phone wants to use optimized charging, but why does it have to wake me up in the process? I can't find a way to tell it to just do what it's going to do and not startle me out of a sound sleep. I can't turn it off due to being on call for work. My hours vary, so I can't set do not disturb times. I just want less dings for things like this.
