This one seems to be the culprit. In the !dev->dbdc_support section.

I updated the commit so that IEEE80211_VHT_CAP_SUPP_CHAN_WIDTH_160MHZ is only set on MT7916, could use testing.

As hnyman pointed out in my similar pull request for mt7915 (RT3200 router) you should amend the forum link in the comment and commit to: https://forum.openwrt.org/t/802-11ax-worse-than-802-11ac-with-mt76-driver/126466

For reference my pull request https://github.com/openwrt/mt76/pull/768

So any news about this? I think we have to solve this problem before 23.05 landing, and it is at RC1 now.
