Ok - pictures are clear. Your DOCSIS mode is 3.1 which means that the heavy work is done by the single upstream and downstream channels; the other channels assisting.
The effective speed of the D3.1 is constrained by the actual speed of the slowest D3.0 channel because they all aggregate at your modem.
In the upstream case, your modulation at 64QAM is the highest available for the D3.0 protocol. The symbol rate is at max too. So theoretically, there is nothing to impair your upstream.
The power level is fine - not surprising since the signal only travels as far as the ONT which then converts to fibre.
Your 80 Meg upstream constraint thus cannot be explained by anything obvious in your stats.
Any neighbours you can consult? Area proof is useful. If they have similar issues, then either there is congestion at an optical node (which VM can easily detect; or there is a rate limiting setting made at the VM end; or there is an area fault invisible to the stats because they measure power to/from the ONT, although SNR is based on the full transit path. If there was noise on the upstream, then the modulation would be automatically lowered commanded from thevVM end. So noise isn’t the problem.
I do think you are entitled to ask the question why you can never reach 100 Meg upstream.
Btw, the Status reports that 3x COE are allowed. Normally that should be just 1. If you still have the Hub 4 and an additional cox port ( via a splitter) it should work although it night need activation by phone call.
