MAXM86161EVSYS: How to get higher output sample rate than 25 sps?

I am using the MAXM86161EVSYS evaluation system (AXM86161 Sensor Hub Software) for PPG measurement at a fingertip. The GUI provides the following sample rate options:
25sps/avg=1, 50sps/avg=2, 100sps/avg=4, 200sps/avg=8, 400sps/avg=16

All of these appear to result in a final effective output rate of 25 Hz. I need at least 100–200 Hz output for PPG morphology analysis (APG second derivative and b/a ratio for cuffless blood pressure estimation).

The MAXM86161 datasheet states the internal ADC supports up to 4096 sps. Is there any way to access higher sample rate raw data from this eval system — for example, through direct register access, alternative firmware, SDK, or a different software tool?

Any guidance would be appreciated. Thank you.
