Hello,
Let's put it this way, changing certain settings in the context of the "vRealize Appliance" in my opinion it is not adequately documented and consequently complicated but there is a VAMI folder that contains some tools that "can be used" for this purpose.
Take this article for example:
https://kb.vmware.com/s/article/2115840
To be on the safe side, in a production context, I would exchange words with technical support.
Regards,
Ferdinando
