2 GPU / 6 Monitor on W10 Pro?

Happy DisplayFusion user since 2015. I had been running 2 GPU / 5+ Monitors without issue for years across several GPU / Monitor combos.

Recently, it seems Windows 10 Pro is having difficulty supporting more than 4 monitors. When I load into Windows, I get hardware interrupt freezes and W10 / DisplayFusion / Nvidia Control Panel all seem to be fighting over which 4 of my 6 monitors is going to display. I'm only able to restore stability by disabling my 2nd GPU in Device Manager.

Is there guidance on how to get all 6 monitors enabled?

GPU 1: RTX 4080 Super
DisplayPort -> ASUS PG27AQN 1440p@60
DisplayPort -> Dell U2717D 1440p@60
DisplayPort -> Dell U2717D 1440p@60 -> DisplayPort 1.2 MST -> Dell S2421HS 1080p@60

GPU 2: GTX 980
DisplayPort -> Dell U2717D 1440p@60 -> DisplayPort 1.2 MST -> Dell S2421HS 1080p@60

That setup should be fine as far as I know. If you still have trouble enabling them all with DisplayFusion exited, it would be an issue with Windows or the NVIDIA drivers. We unfortunately don't have a setup here that we could replicate this configuration with to test though, so can't offer any extra advice there.
