Hi and welcome
You certainly seem to have a stable connection with ample noise margin to spare, so switching off interleaving would probably get you the top connection speed (8128) and an IP profile of 7150 kbps. But there's a degree of uncertainty about the error rate - without a doubt you would get more errors, but how many more you won't know until you try it. So it's a little bit of a risk.
For what it's worth, my personal view is that the speed increase is fairly insignificant in a practical sense, so I would only make the change if I needed lower latency (ping).
