Maybe Oshyan will correct me, but it is not even necessary to use non-adaptive max samples. It is enough to put, for example, 1/64 first samples for First sampling level, and adjust the noise level with the Pixel noise threshold parameter (which is near). Most likely it can be reduced, for example, to 0.03-0.02. It has a very strong effect on rendering time, but it can completely eliminate noise.

...Also if you're using v3 cloud layers, take a look at the newer Voxel Scattering Quality setting in the GI in Clouds tab of the Render GI Settings node...
Does the increase in this parameter always increase the render time? For some reason, in my test scene (two nested a few different cloud layers v3 without any geometric objects) once I got the opposite result - the rendering time decreased when changing the value from 25 to 50 (by 13%). But at the same time, I did not find noise reduction at all. Perhaps I've already sufficiently reduced it in other ways.

The fountains of knowledge that spring up around here...
WASasquatch, there is another way to reduce noise, use Photoshop's AA
. It is enough to render image a larger size than necessary, and then make the rescale down in the PS with suitable resampling settings. True, if the resolution of 1280 × 900 is too small for this, you will have to do several renderings. (About denoisers like Neat Image for PS, I do not need to write, I think - such advice can offend
)
