I am a Tasker enthusiast and when I can automate something simple on my phone I like to. I set a simple task to turn off WiFi when my home network is not detected so my phone doesn't scan and report my location to businesses. However, this functionality is now nonexistent and the developer has to ask people not to one-star their app because it doesn't work. My phone is my phone and killing my ability to use it as such for whatever security theater Google is playing at is why I root my device. Anyone else still rooting for similar reasons?
Rooting a device is a process that depends on the phone and manufacturer. On some devices it is flat out impossible, on other it is trivial (those tend to be increasingly rare). The steps usually go something like this
Keep in mind that you can 100% brick your phone doing this and that it'll most likely void your warranty. Do not root your device following this post alone. I tried to answer an ELI5, not a Teach Me How To Do It Like I'm 5.

Steps 2-3 are sadly impossible on most devices. If you have one of the bad ones, I'd recommend making some searches before you choose your next device.
Does this disable any OEM updates?
It will disable incremental updates but as long as there is a flashable zip file of the full image you can update using that
You can also quickly unroot then do an incremental update and then use magisk to create a flashable boot image afterwards to re-root
