Power levels, SNR and modulation are all ell inside permitted ranges. If there's peak time congestion, then that's bad news. In some cases this is Covid related and may disappear if we ever get back to normal again, equally "over-utilisation" seemed to be creeping up for some people long before Covid became an issue, and VM's track record on resolving this is poor.
Set up aBroadband Quality Monitor. Let it run for 24 hours and then post a link to shared live graph. That'll give us an idea of what's going on, and we can comment accordingly.

No, what @Buffer6 means is that I missed a trick, and he (she) has correctly spotted that your upstream modulation is all over the place, and that's the most likely cause of problems. If you will give them the time to do so (can take a few days) the forum staff will be able to advise.
