I tried out this commit on my Xiaomi Redmi AX6000 with MT7976AN

Unfortunately it doesn't come up at the kernel level. "Could not set channel for kernel driver"

@taylorkline You can try to run every single channel (149, 153, 157, 161, 165, 169, 173 and 177) using HE20 option and see which one is not supported.

So your adapter probably do not support these frequencies. You can verify this using iw reg get command.

Thanks. I'm imagining that hypothetically, I could download

https://patchwork.kernel.org/series/788955/mbox/

And apply to my local build? But I'm not confident enough to risk a brick.

Actually I'm not following. It looks like the series you linked to is merged into openwrt/mt76, e.g.: openwrt/mt76@4a0f839

I forgot that the mt76 driver used is from a separate repository and the changes I mentioned are already applied.
In your case, the problem is probably the NO-IR flag. Discussion on this topic: https://forum.openwrt.org/t/new-indoor-5-ghz-channels/156942

If you don't mind me asking, what is your usecase that allows you to use your device on these channels? You have a non-OpenWrt AP and your OpenWrt device is a client?
