Dock help

[Zazme_Yakuza]

So I was trying to setup for an ios 11 and I was setting it up normally at first, but the dock was in the way and I was trying to click continue in the iPad Analytics step but ,I can't any help guys? I just need to know how to take the dock off the way

I eventually crashed the dock/Springboard /whatever by furiously sweeping, trying to rotate, opening Cover sheet... Or try rebooting until it goes away. There's no other way.
