How can I Mei h. Mate 10 lite rooks?

I would like to roast my Huawei Mate 10 Lite because my father has set up a WLAN lock on our Fritzbox and I would like to change my MAC address and that works if I have rooted my phone but I do not know how to rooten my mobile phone?!

My tip: if you do not know how to do that, either look for someone who knows and can be there, or leave it, the risk is too high:-)

probably. Are there any other options? (Laptop, etc)

That would ask the father for unlocking.

For example ^^

That certainly has his reason why your father did that. And to my knowledge, Huawei has blocked because boatloader on his devices means you can no longer root the devices.

Not at all.

Huawei does not let the lock of the boot loader and you need to rooten.
