Are you looking for something like this?

cat /etc/apt/sources.list /etc/apt/sources.list.d/* | grep -E
'^[^#].*buster.*contrib.*$' > /dev/null 2> /dev/null && contrib=1 || unset
contrib

cat /etc/apt/sources.list /etc/apt/sources.list.d/* | grep -E
'^[^#].*buster.*non-free.*$' > /dev/null 2> /dev/null && nonfree=1 || unset
nonfree

These two lines set the "contrib" and "nonfree" shell variables to 1 if
contrib or non-free are present and uncommented anywhere in the sources list,
or unset them if not.
