How can I tell Nuendo that I always want to use my RME interface?

When I open up Nuendo 11 on my 10.5.7 mac Nuendo always asks me if maybe the internal speakers of one of my monitors, or the internal speaker of the mac may be better for pro audio than my UFX+.
There used to be a drop down menu under studio setup-audio system, but that seems to have vanished…

So is there a way to get this menu back or tell Nuendo once and for all to use the RME over internal speakers?
