Disable "New Audio Device" Popups?

I have two displays connected to my Mac, but don't always have them both switched on at the same time; this is problematic for Discord as when I switch on the second screen, it detects both as new audio devices, and present a popup box asking if I want to switch my audio.

Is there a way to disable this popup? In my Voice and Video settings I've configured specific input and output devices (a wired headset that's always connected), and I've never used either screen as an audio device (one of them doesn't even have speakers, no idea why it registers), so being asked every time is really annoying, as I've never used them, and never want to use them to do audio in Discord.

I've trawled through settings and didn't see anything obvious; have I just missed it somehow? If such an option doesn't exist, then I'd like to suggest a new option "Prompt when new audio/video devices are detected" so that I can turn this off if I want to.

Like I say, I'm specifically using the macOS version of Discord, but this probably applies to all desktop versions (not sure about mobile apps).
