Can I block someone from trying to turn off my phone?

So, last day I was wondering if I have any way to locate my phone if lost. From what I've heard , find my device doesn't work if the device is turned off. So my question is , how can I stop a potential thief from turning off my device when it's locked (lockscreen with pin) ? So I could easily locate it with Find my device , let's say someone stole my phone in a bus he tries to turn it off to avoid it rigging (if we try to call)
