Hi @JuanCarlosrl ,
Based on what you are describing it sounds like you want to create a custom role for users to just create/modify/delete quotas.
You can reference the following links:
I believe the command you are looking for will be similar to this:
security login role create -role (rolename) -cmddirname "volume quota" -access (all,none,readonly)
Let us know if you have any additional questions.
