And so on..
I'm still not sure what you want. What is it you wish the ticket to accomplish?
Splunk does not have "services". Splunk users are given roles and those roles have a number of defined capabilities. The built-in roles, in order of increasing capability, are 'user', 'power user', and 'admin' (on-prem) or 'sc_admin' (Splunk Cloud). The first two items in your list are available only to users with the 'admin' or 'sc_admin' role (or other roles that inherit one of those roles).
The last item on your list is external to Splunk. Splunk upgrades are performed by the OS user that "owns" the software.
