After yum update lost IP address

Dear Team,

Recently I created a VM from one RHEL 8.4 image with a static IP from PowerVC tool. All ok the VM has been created with respective resources. But once i did "yum update" command in the new VM and later when reboot the server lost its IP address. After that I have to manually put the IP address via nmtui and respetive gateway details. But every reboot the same thing happining.

Kindly advise what to resolve this issue or some hint to investigate.

Thank you.
