You really need the 12sp rings, so no cheating here. https://www.bike-discount.de/en/buy/rotor-road-aero-r-rings-2-speed-110x4-spider-mount-chainring-929822
Can you just sell off the Dfour/crank for $400? then buy a Force / Rival PM crankset? The Rival is $350 and a brick; the Force is $700. Both need a DUB BB installed (use SRAMs if you’re BB86)
The other option would be to try the Eagle chain with 11sp rings and 12sp rear derailleur pulley wheels. You might need 12sp eagle 2x rings though. If the chain floats on the rings or makes noise, you need the 12sp rings. AXS Force 10-36 Cassette with Standard 12sp Chain? - Weight Weenies
