If you do use the Dell Update Application, I suggest to go ahead and run the new update as it is supposed to address (fix) DSA-2023-146 and DSA-2023-148, which are security vulnerabilities caused by previous versions, elevated command and InstallShield, I think.  If you are not using Dell Update, just disregard. As for the Realtek Audio driver, verify in Device Manager, as you should have the same version already.  Probably just a fluke in the system scan.  But, if your audio driver is an older version, I suggest to go ahead with the update as that driver was released since 2019 and has been running stable since. 
When I checked the Dell update page and let it search for drivers etc that it thinks I might need, it came up with the following 2 items = Dell Update Windows Universal Application_344NX--WIN_4.9.0_AO1.exe Dated 9 May 2023 and marked as Urgent. Realtec-Audio Driver-T55wp_WIN_6.0.1. 8248_AO7.exe 13 October 2017 My 8930 is running fine and I don't have any problems, just looking for info or experiences some might have had with these two updates, especially the Universal Application. Anybody have any problems with them?
