Wolftooth components makes drop stop chainrings that convert standard 2x cranks to 1x. I converted a Shimano 5800 2x crankset to 1x. Paired with a medium cage Shimano 6800 der. it works very well --- even though the 6800 rear der. has no clutch or extra spring tension. I haven't dropped a chain yet riding on unpaved roads in rural NH. If you already own a compatible 2x crankset, it is a relatively inexpensive upgrade. I also use a Wolftooth Roadlink which allows me to run 11-40 11 speed mountain bike cassette in the back. Go to :https://www.wolftoothcomponents.com/collections/cyclocross-road
Since the Wolftooth chainring requires shorter chainring bolts, you will either have to use spacers, or Wolftooth chainring bolts. While pricey, the Wolftooth alloy replacement bolts are very well made and make the installation very easy. The customer support from Wolftooth is also first rate.
Finally, initially I purchased a 40T Wolftooth; but I found that a the 36T was a better choice for the kind of riding I do. I suggest you focus on the low end of your gear set, rather than the high end. I think that unless your race, you'll like the smaller chainring for the increased low end gearing and smaller jumps at the high end.
My experience with Wolftooth and XT cranks is good. Same for SRAM compatible rings. I have a Wolftooth 1x ring with correct chainline for the Shimano crank and it's been great. I also like the Shimano crank and bottom bracket in general.
