We are hoping to limit our wpa_supplicant to get connections with 20

Usually 40 MHz intolerance is used on 2.4 GHz band. Can we use it for
5 GHz band?
ht40_intolerant=1 does not prevent use of 40 MHz by the local device..
It is trying to make everyone in range not use 40 MHz on 2.4 GHz..
disable_ht40=1 might work for this, if I understood what you are trying
to do correctly.
In case the desire is to have a VHT-20 station on a VHT80 AP, I am not
sure it can be done. disable-ht40 might allow you to have an HT-20 station
on VHT80 AP.
From what I recall, there is no way to advertise a VHT-20 station since the
spec does not allow for a VHT station that cannot do VHT-80.
At least with some driver hacking and proper firmware, it would be possible to
disable all 40 and 80Mhz rates, so the station would always transmit 20Mhz
rates, but it would still be receiving up to 80Mhz wide packets...
Thanks,
