If your only intention is to set the hostname once and stay unchanged
(regardless of any possible side-effects) then the following might be a
solution:
(1) Introduce a new profile, say Dual-IP, using a patch like this one:
diff --git a/etc/dhcp/dhclient-exit-hooks.d/hostname
b/etc/dhcp/dhclient-exit-hooks.d/hostname
old mode 100755
new mode 100644
index ae6718d6..f5247407

IMO this patch wouldn't mess up anything else, but please check.
(2) Configure the workstation:
hostname <wanted name>
hostname > /etc/hostname
sed -i 's#Workstation#Workstation, Dual-IP#' /etc/debian-edu/config
