Direct Routing - Local Media Optimization - External NAT (Trusted IP)

I am planning to configure an SBC with Local Media Optimization to make the traffic of internal users goes directly to the internal IP of the SBC

In the following link:
https://learn.microsoft.com/en-us/microsoftteams/direct-routing-media-optimization

it shows that there is an "External NAT (Trusted IP)" for each subnet

Do I really need to have multiple Public IPs (one for each subnet)?

How to do it to reduce the number of Public IPs?
