New Shimano Di2 Dura-Ace R9200 & Ultegra R8100

Is anyone running 1x on these groupsets with a NW chainring? Does the rear derailleur maintain enough tension to prevent chaindrops?

I am considering switching from SRAM 22 mech groupsets to Di2 on my bikes, and just not sure how i will go without clutched derailleurs on the 1x bikes
