Azure Load Balancing, ATP, Networking Config and/or UFW?

Just curious if anyone has nodes running in Azure and how they run security. I currently have Fail2Ban and UFW on each node, which is further filtered in Azure VM networking and Azure Defender and managed in Azure Security Center. Is it safe to stop using UFW and eliminate that layer of complexity?

Also thinking about switching it all over to Azure Firewall Manager but want to talk to someone who has used it or is also thinking about it.
