If you manually set any of the advanced options such as reference frames or add them to the command line they'll over-ride the chosen speed preset and profile/level. The x264 speed presets won't over-ride the profile/level though, so to be sure it's compliant you might want to use the veryslow or placebo speed preset to get the maximum number of reference frames while setting the level 3.2. You can still change any of the other options if you don't want to use the exact speed preset settings (number of b frames etc). I'm pretty sure that'll work.

I gather some decoders check the video stream differently to others. For instance MPC-HC's DXVA decoder has options to do a full check, skip the level check, skip the ref frames check or not check anything. By default it just skips the level check but I guess different decoders might do it differently.
