Its worse then that. First the base Nvidia driver isn't much different across the different products. The problem that you may not realize is Support Assistant is trying to install a driver that is nearly 2 months old. If you up to date on your Nvidia drivers through Nvidia them selves the Dell driver is the wrong driver to be installed!
I have a G15 with Nvidia 3060 GPU running a U2720QM 4K monitor running in 4K.  I am using the studio driver because I run Photoshop and Lightroom and not games.  The Dell Support Assistant wants me to update my Nvidia Driver but wants to download only the standard gaming driver which I have replaced with the studio driver.   Is there any way to tell the Support Assistant not to look for the gaming driver and to rather look for the studio driver? Or do I just have to go on ignoring the driver download by unchecking the box?
