Subfloor for lamiate drops/dips in front of basement stairs

My husband needs help and he is too stubborn to ask for help, so I will do it for him

We started installing laminate floor in our living room and ran into issues.

He checked the floor level but must have missed the spot right in front of the staircase the leads to our basement.

The dip is around 1/2" when measuring from highest point on the floor to the front of the thread. The floor starts dipping around 40" in front of the thread.

The subfloor is made out of plywood and the laminate we are installing is 12mm thick (+3mm attached pad).

He wants to reduce/remove the dip by adding some plywood under the couple of laminate boards in front of the staircase. From some of the posts I have seen people tend to us some leveling product instead.

What would be the best approach? Any information or help from some of you lovely gentlemen would be greatly appreciated

Why does the sub floor dip? You can't just use plywood as a shim, you'd have a lip to overcome at the edge of the plywood. Is there access to the floor framing from below?
