how to change bios setting to Disable "High Resolution mode when connected to a USB-C DP

[JLMCZ]

Hello, I have a Dell Monitor connected to my HP laptop. I am having issues with internet dropouts all the time. Dell Support notice states I need to Disable in the BIOS. I am unable to determine what in the BIOS I need to change as its not spelled out as below.  Looking for directions/video on how I can change the BIOS to achieve this below action?

• BIOS setting for "Enable High Resolution mode when connected to a USB-C DP alt mode dock" is Disabled or unchecked. Disabled or unchecked should mean that the computer is using High Data.

Non-Dell BIOS settings resolution: Note:

• If using an HP computer, ensure that the BIOS setting for "Enable High Resolution mode when connected to a USB-C DP alt mode dock" is Disabled or unchecked. Disabled or unchecked should mean that the computer is using High Data.
