ymmv, but I would recommend uninstalling the NVidia app as it’s still a bit dodgy. Just use NVidia Control Panel to set a global performance profile (there’s debate over doing individual game profiles as well, but I can’t be bothered doing that anymore and just use global) and use Nvidia Profile Inspector to set a global DLSS4 override for all games that use DLSS.

Doing it this way you always have the latest DLSS4 as deployed by NVidia, and once a game is configured for DLSS4 you should be fine, as it appears MSFS 2024 now is with SU2.
With NVidia profile inspector you can import/export the settings to quickly reconfigure the NVidia Control Panel when testing, which is handy as its UI is slow.
