I have a similar problem, my modem will work perfectly till 9:30 AM Eastern Time. It will act irradically till around noon, and then flaulessly till 9:30 AM the next morning. I have documented this. Like the original poster, Comcast has consistantly refused to check out the house cables, claiming Covid19 concerns, even working outside the house.

You'll have to keep checking with the ISP about this. They need to check there services up to the modem.

So I go the new splitter (Extreme BDS102H, same as what was installed by Comcast) from Amazon yesterday, and also found another brand splitter I had laying around in my basement (Antronix CMC2002H-A). I compiled the power and SNR changes into a PDF (attached). I have decided to try the Antronix splitter for now to see if that makes a difference, even though the SNR got a little worse than using the comcast provided brand (but power did increase). I really don't suspect this is going to fix my issue, but will know by the end of this week and I'll keep you posted.
Summary:
- Replacing original splitter (Extreme) with identical new one resulted in an increase in power, but a decrease in SNR for downstream (no big change in upstream).
- Replacing original splitter with a different brand (Antronix) resulted in an increase in power, but a decrease in SNR for downstream (no big change in upstream).
- Removing splitter resulted in a big increase in power, but a decrease in SNR for downstream (with a decrease in power for upstream).
If anyone has any suggestions on how to get proper support from Comcast during this pandemic, please let me know. Thanks!

Still experiencing internet connection drops on occasion, and some channels on our TV are still pixelated. Oh well. Will try to get Comcast to come out some day once this pandemic is over.
