Is there any option to have 'dpkg --get-selections' NOT include

No, dpkg has no notion of automatically installed packages, that is an
apt concept.
Otherwise, all packages show as manually installed, including those
that would otherwise have been automatically installed.
You can obtain a list of automatically installed packages with
apt-mark(1):
$ apt-mark showauto > automatically-installed-packages
Then, on the replicated system where you presumably had used
"dpkg --set-selections" to install the same set of packages:
# apt-mark auto $(cat automatically-installed-packages)
