My Ipad pro is not responsive to touch. I want to shut it down and restart. Any way to shut down without slide touch (because touch does not work?

Try this. It’s called a forced restart.

• iPad models with Face ID: Press and quickly release the Volume Up button. Press and quickly release the Volume Down button. Then press and hold the Power button until the device restarts.
• iPad with Home button, iPhone 6s or earlier, and iPod touch (6th generation) or earlier: Press and hold both the Home and the Top (or Side) buttons until you see the Apple logo.
