Disable external sharing for one group, but not another

It seems that I can only find global settings regarding group setup. I am looking for a way to disable external link sharing emailing of links outside of the nextcloud install for one group, but allow it for another group. Is this a supported function? I looked at tags and workflows, but it didn’t seem like it was possible. Is there another way to do it. Is this something in NC12?

Example:

Group A = no external sharing by link or email
Group B = external sharing by link or email allowed
