Disable the tuned Service

If your cluster hosts are running RHEL/CentOS 7.x, disable the "tuned" service by running the following commands:

Ensure that the tuned service is started:
```
systemctl start tuned
```
Turn the tuned service off:
```
tuned-adm off
```
Ensure that there are no active profiles:
```
tuned-adm list
```
The output should contain the following line:
```
No current active profile
```

Shutdown and disable the tuned service:

systemctl stop tuned
systemctl disable tuned
