I would like to update the driver of the Intel UHD Graphics, but I can't find this GPU in the device manager. As an additional GPU I have an RTX 2070 S.
Go to the top:
View → hidden ads (or something like that)
In any case, all hidden objects can be displayed in the Device Manager. Then you will find your IGPU.

Updates itself when there's something to update.
Can I use a program that recognizes where drivers are not up to date / missing and where you can download them. You just have to install it yourself and that's my problem.
