I was able to get Developer Mode option in Privacy&Settings following these steps (watchOS 9.3):
0.) I turned on developer mode on my iPhone
1.) I tried to run watchOS app from Xcode on my watch although it said its unavailable
2.) I turned off developer mode on my iPhone and they turned it back on
3.) Tried to run app watchOS app from Xcode again on my watch, this time I got error massage that I need to turn on developer mode
4.) I went back to Privacy&Settings on my watch I Developer Mode appeared on the bottom
Hope this helps!
