Huawei P9 rooten (Bootloader locked)?

I recently bought a Huawei P9.

The problem is that the official Huawei Bootloader Unlock page was abolished.

Now I do not know if there are still methods how to play a root without unlocked bootloader.

If necessary, I also like to get tips on how to lure my bootloader without having to pay any unlock code for the bootloader.

Well as I said I do not have unlock code for the boot loader and the official page to get the code would be set so that brings nothing.
