I'm not sure about the world embracing 1x11, or 12. Personally, I don't recommend 1x11 (or 1x12) setups even for gravel. Most friends who started with this combination either need to change the chainring size several times a year (depending on the events planned) or have gone back to doubles. It's difficult to improve on a 46 & 33 combination with a 11-36 cassette on gravel (yes, I mean 33, they are available for a 110 BCD crank).

But if a 1x12 with drop bars is the combination you seek, ​​​​​​and you want want the the latest eTap technology: see...

(Sram) "recommend(s) combining a pair of AXS drop bar levers with an Eagle AXS rear derailleur, Eagle chain, 10-50t Eagle cassette, and your choice of either an Eagle or road AXS 1x crankset to build the raddest drop bar bike on the block".
