I have tried it and the best result on my side is in game AA OFF and force FXAA through driver and I use the reshade "Clear Hunter" preset with it that also includes MXAO in this particular preset.
I tested it on an edge of stairs in the hub very close to the camera and TAA just blurs everything out, in game FXAA is not good enough to remove jaggies but driver FXAA seems to be better combined with the rest above gives me the best image quality I can have. Also forced through driver the AF up to 16X and set image quality to highest.
