XS max screen unlock

hello,

my XS max screen was almost crashed in an accident.

the remaining part of the survived screen is not responsive to the touch.

all I wanted to backup the iphone and then restore on another iphone device i have.

the problem now is that I have to unlock the screen to connect to the itunes in the authorized computer .

I tried to to use siri to enable voice over, but siri is not responding at all.

is there anyway to connect an external keyboard or what soever just to enter the passcode?!!!
