Yes, you can remove the second cable, as they both function independently.
I'm guessing both cables are on a wallplate, so are you just talking about disconnecting one cable flylead from the wallplate, or are you talking about removing the whole cable run from the LNB?
I wouldn't suggest doing the latter, as you may possibly use it later, for a dual tuner, a second VAST decoder, or just as a back-up. Removing a flylead from the wallplate... no problem.
If your VAST signals are working OK, I would suggest there's no need for any adjustment to the LNB.
When Foxtel installs dishes, the LNB is optimised for their horizontally-polarised signals, so a slight tweek on the vertical VAST signals can help, but only if they are intermittent now.
Adjusting the LNB would require you being able to see a signal quality scale on a meter or screen connected at the dish and adjusting LNB skew whilst tuned to a VAST transponder to obtain the highest signal quality (highest MER/lowest BER).
As I said, if it's working, no need to do anything.
Your Humax is still a current model and firmware updates are automatic over the air, as far as I'm aware.
If it's working, I personally wouldn't be changing anything.
