Can we are able to turn off wifi and bluetooth from control centre completely , it turns off for 24 hrs only from control centre

Not from the Control Center. See the following from Use Bluetooth and Wi-Fi in Control Center with iOS 11 - Apple Support

If you want to completely disable Wi-Fi and Bluetooth for all networks and devices, follow these steps:

• To turn off Wi-Fi, go to Settings > Wi-Fi and turn off Wi-Fi.
• To turn off Bluetooth, go to Settings > Bluetooth and turn off Bluetooth.

For the best experience on your iOS device, try to keep Wi-Fi and Bluetooth turned on.

Airplane Mode may also turn off Wi-Fi and Bluetooth, unless you turned them on while in Airplane Mode. Learn more about how to use Wi-Fi and Bluetooth in Airplane Mode.

“Hey Siri! Turn off my wi-fi.”
