Black screen after install nvidia 460 driver on Parrot OS

I am trying to install nvidia-driver (460) on my Parrot OS/Debian 9 on my laptop.

After a lot of failed attempts to install drivers properly I followed this instruction, which seemed good:

Driver seems to be installed fine.
But you have bbswitch installed. Remove that.
Then as your laptop has an integrated GPU, you should configure a “Prime” profile:

how i can remove bbswitch correctly? thanks for reply

I think the packages is called bbswitch-dkms.
sudo apt purge bbswitch-dkms
