In android there is a command to boot up a sim without a head or window which takes up significantly less ram e.g.

emulator -avd Pixel2Four_API_27 -no-window -no-audio -no-snapshot-load

Is there such a mode for iOS sims?

Thanks

To launch a simulator in headless mode, for example an iPhone 11 : 

xcrun simctl boot iPhone\ 11

If you want the list of all simulator available, use this command :

instruments -s devices

At any moment, you can see the UI of your simulator by launching the simulator app : 

open /Applications/Xcode.app/Contents/Developer/Applications/Simulator.app/
