Windows Lock Screen Enters Standby After 1 Minute Due to Dell Optimizer Proximity Sensor

Hello,
Dell Optimizer VS 3.2.212.0 came installed on my new Dell.  Upon starting up the Lock Screen goes into standby mode within less than 1 minute.

The fix from Dell is to select the Proximity Sensor within Dell Optimizer App-which DOES NOT exist.

Can I uninstall Dell Optimizer to eliminate this issue?  If YES - Do I need to uninstall another other associated Dell Support apps like

Support Assist?

AND/OR 

Dell Peripheral Manager?

AND/OR

Dell Command, etc.?

Please read all the above to advise on all questions.

Thank you.
