B1265DNF Mac OS11 Big Sur

I have a perfectly functioning B1265DNF. This is an early Airprint capable printer/scanner, so clearly oriented to Mac users. I want to continue using it, but it scanning functionality is lost in Big Sur. Printer can be added through normal Mac process, but no scanning functionality is available. I tried using Dell's last available software package from 2017, but it's only useable up to OSX.

Is there a basic Big Sur Dell driver that would give me scanning functionality?

I'm really trying to keep this out of the landfill. It's a real shame that this isn't a priority given Dell's CSR reporting.
