How to configure so the Linux CentOS v8 VM I have with static IP address?

I have already set the networking parameter during the GUI installation, but after the reboot, it still reverting back with DHCP IP addressing?

Do I have to create a new interface file rather than modifying the below:

```
 cat /etc/sysconfig/network-scripts/ifcfg-ens192

```

Note: I cannot even restart the network service as mentioned in the various blog:

```
[root@PRDSIEM01-VM etc]# systemctl restart network
Failed to restart network.service: Unit network.service not found.

```
