when i download a plugin, say dagster, and then change the

pip_url: pendulum<3

or add something like that in the

meltano.yml

config, do i then need to install that plugin again with

meltano install plugins

or `meltano install utilities`to get the new configs to work in my project?

Yes, you do need to reinstall a plugin if you change its `pip_url`:

meltano install --clean utility dagster
