Windows only updates the bootloader, it doesn't touch Linux partitions. After an update you just have to fix the bootloader again which isn't too hard if you know how it works.
As in tradition - mindset. Getting on Linux requires a certain mindset, and this gets more and more true the weirder and more involved whatever it is that you are planning to do gets.
The best way to learn how it works is to mess with it. I have reinstalled my Surface Go 2 numerous times because I messed something up. After leaving Windows I have used dual boot with Arch and Chrome OS for a while, and now I just use Arch including secureboot enabled.
