This seems like a rare event. At the time, Caruana was rated 2640 FIDE with Berg's rating at 2623.
In games between 2600+ players, are there any classical games with 4 pieces (for the same player) pinned on the same rank?
If not, are there other classical games between top players with 3 pieces pinned on the same rank?
As depicted, there are no restrictions on the type of pin.
Example: As proof that this is geometrically possible, I offer the following constructed example in the interests of clarity:
