Due to it being a radio licenced by rule, the firmware in wifi devices is locked down tight. If it ware wide open FCC would revoke it's type acceptance.
The only project that so far has managed to even partially use wifi hardware as a more generic SDR is nexmon[1] and even that is rather involved.
Really cool project but not much heard since 2018.
For just experimenting with modems across a noisy path one could just use the built in microphone and speakers.
