My experience with Windows 10 was me turning off the "Bing" features, and one day turning on my computer and discovering overnight with an automatic update Microsoft had turned them back on, and everything I typed into the Start search was being forwarded to a network service. This happened more than once.
It won't be enough to turn Windows 11's "AI" surveillance features off. Based on how they behaved with Win10, you have to assume a feature you turn off today will be silently turned on later.
