Yes, yes there is. The port is literally part of the enclosure. I will see if I have any construction pictures to show you why. The port is held in on FOUR sides with PL Premium--front, top, and sides. Remember it's not tubes, it's a slot in the top and bottom, with a vertical brace from the top/bottom of the enclosure to the middle of the port. So literally, it's not going to happen unless someone wants to use a rasp on it for a couple days. Even then, the inside of the cab is so heavily braced you probably can't get your hand in there at all.
I'll see what I can come up with. I don't think a 4Hz deviation in the tuning frequency is going to make such a major difference in sound? But maybe I'm wrong...

Before you start cutting up the box (which I would not recommend) you need know one thing. The box is too small for the speakers, which is why the frequency response chart in SMAART offers a steady decline like walking down a hill.
You can re-tune the box as often as you like however, it will not offer an improvement for the woofers need more space.

The Qts requires a big box The fs is too high to be classed as a subwoofer
Don't expect more than 700 watts from each driver under long-term conditions. Power compression comes into play above 700 watts at frequencies ranging from 66 - 51.7 Hertz.

Here is your measured chart

You seem very happy with the sound of the box. I would not recommend you alter the tuning. As I explained to you in January, those speakers require a big box. That is the only way to achieve a flatter, more extended response when measured in SMAART.
Enjoy the cabinet gain of the box and, leave the tuning alone.
How was the bass track I sent on your Lab Subs?
