Are you referring how it does a `brew upgrade` when doing a `brew install`? It should tell you how to disable that whenever it happens:

> Adjust how often this is run with `$HOMEBREW_AUTO_UPDATE_SECS` or disable with

> `$HOMEBREW_NO_AUTO_UPDATE=1`. Hide these hints with `$HOMEBREW_NO_ENV_HINTS=1` (see `man brew`).

Why is this not the default? I removed homebrew years ago, because it was just full of nasty surprises like this. Does homebrew still share dependencies? Previously you could not have package A with a transitive dependency of lib-X = v1.2 and B that requires lib-X = v.0.7.
