DCE is provided in the form of an appliance. Customers do not in general have access to the operating system thus modules which are not essential to the functioning DCE software cannot be installed. Even if it were installed, its unlikely you'd have access to the modules and their features as OS level access is not provided.
For ITA, customers may deploy their own Redhat 8.x or Rocky Linux 8.x OS (CentOS 8.x if ITA is a 9.x release prior to 9.3.0). Customers are permitted to install other tools and modules as they need as long as those tools do not interfere with the IT Advisor application. We have a number of customers who deploy their own malware tools, log collection or backups tools on their ITA server. So you are free to install the tools you mention as long as they do not break IT Advisor.
As a policy for ITA, Schneider tries to offer the modules needed for general use of IT Advisor so we do not usually include third party modules like the ones you specified
