dhclient not found in RHEL 8.4 anaconda prescript

Hello,
I run a prescript in the RHEL 8.4 installer (anaconda).
This script that includes the command "dhclient" fails because dhclient is not found by the RHEL 8.4 installer.
The result is that I am not able to connect to the network.
I verified that dhclient is available in RHEL 8.3 or older installers and also in RHEL 8.4 OS (not the installer).
Can you indicate a way to obtain a dynamic IP in the anaconda prescript?
Thanks
Mariano
