How to prevent Deno from automatic dependencies installation during `deno task`? Why does it happen?

Hey! I have a few problems with deps and 
deno task
.

One is, I have my own 
install
 task that is running 
deno install
 with certain arguments (e.g. 
--allow-scripts
, 
--env-file
 etc). However, if I run 
deno task install
, it first installs the dependencies, before running my task. This is confusing and I don't know how to disable it.

Another is, Deno unexpectedly updates the lockfile when I don't ask it to. Here is a failing workflow: link. After installing packages with 
deno install
 (with frozen lockfile) in the workspace root, everything is fine. However, when running a task from a workspace member at 
tests/node
 (the command is 
vitest run
), Deno errors me that the lockfile is out of date - for some reason, it wants to add another entry for 
npm:vitest
.

So, first, I am curious why is it that Deno installs packages during 
deno task
 in the first place, and second, why this behaviour is inconsistent in the workspace?
