How to bias WiFi rate-control selection?

[Bryght-Richard]

I'm working on a product where more deterministic latency for sending occasional small packets is more important than throughput. I don't want to disable specific MCS values or enforce a fixed rate(like esp_wifi_internal_set_fix_rate()). On another radio IC, I was able to bias the rate-control algorithm by specifying a dB offset to skew the rate control selector. Effectively, I'd like to prefer TX MCS to be 1-2 settings lower than it would be naturally. Is there anything like this in the ESP-IDF?
