What do you specifically want to change? There are multiple ways to go about most changes, some easier than others. WiFi tends to have other (non-device-tree) issues, e.g., some WiFi needs an extra firmware package (e.g., see https://www.intel.com/content/www/us/en/support/articles/000005511/network-and-i-o/wireless-networking.html).
I do not personally use the WiFi so there isn’t much I can say about configuring a specific WiFi solution, but unless this is something built in to a custom carrier board, then device tree changes would not be needed. If this is a WiFi question, then probably a new thread on that topic would be the way to start (providing the output of “iwconfig”, “ifconfig”, and “cat /proc/cmdline” in the new thread).
