Its not an OS update, its a Google Play Services update .. so if they still apply you would get it
I found it strange that things like 'prettier settings screens' and 'improved connection with cars and watches' would be included in Google Play Services. Surely those things are part of the OS not part of a thing which helps you access the Play store?
I've been using a LineageOS (prev. Cyanogenmod) phone for years and have never installed any google stuff so I don't get these updates anyway.
One possible option would be to install Netguard (open source Android firewall that doesn't require root) and block Play Services.
I have that on a spare unrooted Android phone. Seems to be working so far. But I'm sure Google could bypass it if they really wanted to. I don't know if they've ever made an effort to bypass Netguard (or similar) in the past.
