Hi Mouhssine,
Thank you for your update.
I found a solution using CLI method that we can change the init parameter file in DE and able to complete the change in DE and it will be effective after the VDB refresh only.
Below are the steps followed and it worked fine.
login to DE CLI as delphix_admin
source "db_name"
update
set configParams.<name>=<value>
commit
