As I understand, when the external interface of a firewall is being

the external interface of the firewall.

Recently, a security consultant explained to me that the stealth mode
of a firewall is meant just that the firewall does not respond to ICMP
only, therefore when the firewall is scanned, the services published
using that IP address are still visible/reported.

Both your understanding, the explaination and the "stealth mode" itself
are nonsense.

So then help them smart guy instead of insulting them, or is that all
you can do?
