Possible to disable SAE and force WPA2-PSK-AES on wpa_supplicant v2.10?

Where would I check the value of `ieee80211w` or `pmf` on a stock Linux Mint 21 or Ubuntu 22.04 machine, and how would I modify it? I'd like to be able to change what I need to through `nmcli` if possible.

When I start a hotspot with the commands below, it can be joined by most devices (Linux, Windows, iOS) but not an M1 MacBook Pro. I've determined that this is because of SAE/WPA3 support: if I run macOS's `airport` CLI utility, I see that the wpa_supplicant 2.10 hotspot offers `WPA(PSK/AES/AES) RSN(PSK,PSK-SHA256,SAE/AES/AES)` in the Security column. When I use wpa_supplicant 2.9, it offers `WPA(PSK/AES/AES) RSN(PSK,PSK-SHA256/AES/AES)`, and the MacBook can join.
