Chage hotkeys for disk tray?

Is it possible to change the hotkeys for open tray and close tray? Each time I hit the volume up and down buttons on my MCE remote it pops up on the Retrarch window (open tray/close tray or open/close tray isn’t support on this core) Kinda annoying and I can’t find any way to change the keys.

Sure you can, it’s right there under input settings

I tried that and I still get the notifications.
