A must do.
Even though considered non interference NO professional would tempt fate*and suggest otherwise.

I agree with Kev as everyone here would I am sure. That does not mean you can't do it now at 86k or that it will self destruct at 91K. But you should certainly do it soon after 90K and for sure before 100K.

An engine designated non-interference may have notched pistons and other tweaks to make it such. After time, carbon deposits can make those indentations a little smaller and that can lead to interference. Another reason to change the belt.
