What tool are you using to determine what the bitrate mode is? I can tell you the parameter that controls the bitrate mode in the AAC encoder MFT (CODECAPI_AVEncAACEnableVBR, which is false by default), but I cannot tell what ffmpeg is passing to the MFT.
Yes, the AAC encoder MFT uses constant bitrate mode encoding by default.
