Hi @apangeles
You can create an "application gateway" like below. Create Resource > Application gateway or Create a WAF

Note: You don't need to be a tenant administrator. But you should have permission for any active subscription with the allocated resource group
Every company IT team has the same problem. From my experience, it always ends with the contention of what you are trying to do. When taking this with IT, don't veer your point.
One thing I can assure you is it doesn't affect the whole organization. As an environment administrator with relevant Azure resource group access, you can maintain the DRS Rules. If possible a bit of PP administrator is also handy.
Hope it helps.
