Changing Google Nest Thread Channels

Has anyone been able to change the channel Google Nest devices use for thread?

I haven’t had any success so far. There’s no setting in the Google Home app. For some reason Google decided to pick channel 14 which is horrible because I’m in a dense wifi deployment with all 3 bands (1,6,11) in use.

I’ve been able to successfully join my Sonoff-E OTBR to the same NEST-PAN-* network by extracting the network key. However, even when forcing my OTBR instance to be a thread leader and then changing the channel to 25 or 26, only my OTBR device will change to that channel and the Google devices will more or less ignore the new dataset.

Any ideas? I’m tempted to just deploy a bunch of ESP32-S3/H2 border routers but was hoping that I’d be able to just use my existing hardware!

It’s a shame to find this thread with no reply! Presumably that means that the answer is no!
